Gene Description

LRP1 encodes low-density lipoprotein receptor-related protein 1, a large LDL receptor-family type I membrane receptor that is proteolytically processed into extracellular ligand-binding and membrane/cytoplasmic subunits. LRP1 acts as a multifunctional endocytic, cargo, scavenger, apolipoprotein/lipoprotein, and alpha-2-macroglobulin receptor, concentrating ligands at the plasma membrane and clathrin-coated pits for receptor-mediated internalization, endosomal trafficking, lysosomal clearance, phagocytosis, and lipid transport. In Alzheimer-relevant biology, LRP1 participates in amyloid-beta binding, clearance, and transcytosis across vascular and cellular barriers, and UniProt also describes it as a tau/MAPT receptor controlling tau endocytosis and spread.

Reason: For GO:0005515 (protein binding), the IPI annotation with qualifier enables from PMID:21054788 may reflect a real assay result or interaction, but this GO term does not identify the specific receptor, ligand-binding, cargo-clearance, endocytic, or localization annotation that explains LRP1's role in LDLR-family ligand binding and receptor-mediated internalization/clearance of lipoprotein, apolipoprotein, protease-inhibitor, amyloid-beta, tau, and other cargo complexes. More informative gene-specific annotations are present, so this is marked over-annotated rather than accepted as a core function.

GO_REF:0000024
ACCEPT
Summary: amyloid-beta clearance by transcytosis is retained as a core biological-process annotation for LRP1; it captures process participation within the synthesized core biology: LRP1 cell-surface/coated-pit/endosomal receptor biology, ligand and calcium binding, apolipoprotein/lipoprotein and alpha-2-macroglobulin cargo recognition, receptor-mediated endocytosis, transcytosis, phagocytic/lysosomal clearance, and Alzheimer-relevant amyloid-beta/tau handling.
Reason: For GO:0150093 (amyloid-beta clearance by transcytosis), the ISS annotation with qualifier involved_in from GO_REF:0000024 is consistent with LRP1's core role in LDLR-family ligand binding and receptor-mediated internalization/clearance of lipoprotein, apolipoprotein, protease-inhibitor, amyloid-beta, tau, and other cargo complexes.

MARK AS OVER ANNOTATED
Summary: protein binding is marked over-annotated for LRP1 because this molecular-function term is too generic, interaction-map-like, or weakly informative relative to the gene-specific biology: LRP1 cell-surface/coated-pit/endosomal receptor biology, ligand and calcium binding, apolipoprotein/lipoprotein and alpha-2-macroglobulin cargo recognition, receptor-mediated endocytosis, transcytosis, phagocytic/lysosomal clearance, and Alzheimer-relevant amyloid-beta/tau handling.
Reason: For GO:0005515 (protein binding), the IPI annotation with qualifier enables from PMID:10772929 may reflect a real assay result or interaction, but this GO term does not identify the specific receptor, ligand-binding, cargo-clearance, endocytic, or localization annotation that explains LRP1's role in LDLR-family ligand binding and receptor-mediated internalization/clearance of lipoprotein, apolipoprotein, protease-inhibitor, amyloid-beta, tau, and other cargo complexes. More informative gene-specific annotations are present, so this is marked over-annotated rather than accepted as a core function.

GO:0002265 astrocyte activation involved in immune response
ISS
GO_REF:0000024
KEEP AS NON CORE
Summary: astrocyte activation involved in immune response is retained as a non-core biological-process annotation for LRP1; it records a supported context, interaction, localization, or pathway branch that is secondary to LRP1 cell-surface/coated-pit/endosomal receptor biology, ligand and calcium binding, apolipoprotein/lipoprotein and alpha-2-macroglobulin cargo recognition, receptor-mediated endocytosis, transcytosis, phagocytic/lysosomal clearance, and Alzheimer-relevant amyloid-beta/tau handling.
Reason: For GO:0002265 (astrocyte activation involved in immune response), the ISS annotation with qualifier involved_in from GO_REF:0000024 supports retaining the annotation, but the term describes a context-specific outcome or peripheral branch rather than the principal LRP1 function: LDLR-family ligand binding and receptor-mediated internalization/clearance of lipoprotein, apolipoprotein, protease-inhibitor, amyloid-beta, tau, and other cargo complexes.

Summary: regulation of extracellular matrix disassembly is retained as a non-core biological-process annotation for LRP1; it records a supported context, interaction, localization, or pathway branch that is secondary to LRP1 cell-surface/coated-pit/endosomal receptor biology, ligand and calcium binding, apolipoprotein/lipoprotein and alpha-2-macroglobulin cargo recognition, receptor-mediated endocytosis, transcytosis, phagocytic/lysosomal clearance, and Alzheimer-relevant amyloid-beta/tau handling.

Summary: lipoprotein transport is retained as a core biological-process annotation for LRP1; it captures process participation within the synthesized core biology: LRP1 cell-surface/coated-pit/endosomal receptor biology, ligand and calcium binding, apolipoprotein/lipoprotein and alpha-2-macroglobulin cargo recognition, receptor-mediated endocytosis, transcytosis, phagocytic/lysosomal clearance, and Alzheimer-relevant amyloid-beta/tau handling.
Reason: For GO:0042953 (lipoprotein transport), the NAS annotation with qualifier involved_in from PMID:3266596 is consistent with LRP1's core role in LDLR-family ligand binding and receptor-mediated internalization/clearance of lipoprotein, apolipoprotein, protease-inhibitor, amyloid-beta, tau, and other cargo complexes. This action keeps the term because it provides a specific, evidence-backed receptor, ligand-binding, cargo-clearance, endocytic, or localization annotation rather than only a downstream phenotype or generic interaction label.

MARK AS OVER ANNOTATED
Summary: protein-containing complex binding is marked over-annotated for LRP1 because this molecular-function term is too generic, interaction-map-like, or weakly informative relative to the gene-specific biology: LRP1 cell-surface/coated-pit/endosomal receptor biology, ligand and calcium binding, apolipoprotein/lipoprotein and alpha-2-macroglobulin cargo recognition, receptor-mediated endocytosis, transcytosis, phagocytic/lysosomal clearance, and Alzheimer-relevant amyloid-beta/tau handling.
Reason: For GO:0044877 (protein-containing complex binding), the IDA annotation with qualifier enables from PMID:8626514 may reflect a real assay result or interaction, but this GO term does not identify the specific receptor, ligand-binding, cargo-clearance, endocytic, or localization annotation that explains LRP1's role in LDLR-family ligand binding and receptor-mediated internalization/clearance of lipoprotein, apolipoprotein, protease-inhibitor, amyloid-beta, tau, and other cargo complexes. More informative gene-specific annotations are present, so this is marked over-annotated rather than accepted as a core function.
GO:0010875 positive regulation of cholesterol efflux
ISS
GO_REF:0000024
ACCEPT
Summary: positive regulation of cholesterol efflux is retained as a core biological-process annotation for LRP1; it captures process participation within the synthesized core biology: LRP1 cell-surface/coated-pit/endosomal receptor biology, ligand and calcium binding, apolipoprotein/lipoprotein and alpha-2-macroglobulin cargo recognition, receptor-mediated endocytosis, transcytosis, phagocytic/lysosomal clearance, and Alzheimer-relevant amyloid-beta/tau handling.
Reason: For GO:0010875 (positive regulation of cholesterol efflux), the ISS annotation with qualifier involved_in from GO_REF:0000024 is consistent with LRP1's core role in LDLR-family ligand binding and receptor-mediated internalization/clearance of lipoprotein, apolipoprotein, protease-inhibitor, amyloid-beta, tau, and other cargo complexes. This action keeps the term because it provides a specific, evidence-backed receptor, ligand-binding, cargo-clearance, endocytic, or localization annotation rather than only a downstream phenotype or generic interaction label.
GO:0030178 negative regulation of Wnt signaling pathway
ISS
GO_REF:0000024
KEEP AS NON CORE
Summary: negative regulation of Wnt signaling pathway is retained as a non-core biological-process annotation for LRP1; it records a supported context, interaction, localization, or pathway branch that is secondary to LRP1 cell-surface/coated-pit/endosomal receptor biology, ligand and calcium binding, apolipoprotein/lipoprotein and alpha-2-macroglobulin cargo recognition, receptor-mediated endocytosis, transcytosis, phagocytic/lysosomal clearance, and Alzheimer-relevant amyloid-beta/tau handling.
Reason: For GO:0030178 (negative regulation of Wnt signaling pathway), the ISS annotation with qualifier involved_in from GO_REF:0000024 supports retaining the annotation, but the term describes a context-specific outcome or peripheral branch rather than the principal LRP1 function: LDLR-family ligand binding and receptor-mediated internalization/clearance of lipoprotein, apolipoprotein, protease-inhibitor, amyloid-beta, tau, and other cargo complexes. Keeping it as non-core prevents broad pathway participation from being promoted to core function.
GO:0032370 positive regulation of lipid transport
ISS
GO_REF:0000024
ACCEPT
Summary: positive regulation of lipid transport is retained as a core biological-process annotation for LRP1; it captures process participation within the synthesized core biology: LRP1 cell-surface/coated-pit/endosomal receptor biology, ligand and calcium binding, apolipoprotein/lipoprotein and alpha-2-macroglobulin cargo recognition, receptor-mediated endocytosis, transcytosis, phagocytic/lysosomal clearance, and Alzheimer-relevant amyloid-beta/tau handling.
Reason: For GO:0032370 (positive regulation of lipid transport), the ISS annotation with qualifier involved_in from GO_REF:0000024 is consistent with LRP1's core role in LDLR-family ligand binding and receptor-mediated internalization/clearance of lipoprotein, apolipoprotein, protease-inhibitor, amyloid-beta, tau, and other cargo complexes. This action keeps the term because it provides a specific, evidence-backed receptor, ligand-binding, cargo-clearance, endocytic, or localization annotation rather than only a downstream phenotype or generic interaction label.
GO:0043277 apoptotic cell clearance
ISS
GO_REF:0000024
ACCEPT
Summary: apoptotic cell clearance is retained as a core biological-process annotation for LRP1; it captures process participation within the synthesized core biology: LRP1 cell-surface/coated-pit/endosomal receptor biology, ligand and calcium binding, apolipoprotein/lipoprotein and alpha-2-macroglobulin cargo recognition, receptor-mediated endocytosis, transcytosis, phagocytic/lysosomal clearance, and Alzheimer-relevant amyloid-beta/tau handling.
Reason: For GO:0043277 (apoptotic cell clearance), the ISS annotation with qualifier involved_in from GO_REF:0000024 is consistent with LRP1's core role in LDLR-family ligand binding and receptor-mediated internalization/clearance of lipoprotein, apolipoprotein, protease-inhibitor, amyloid-beta, tau, and other cargo complexes. This action keeps the term because it provides a specific, evidence-backed receptor, ligand-binding, cargo-clearance, endocytic, or localization annotation rather than only a downstream phenotype or generic interaction label.

ACCEPT
Summary: apolipoprotein binding is retained as a core molecular-function annotation for LRP1; it captures activity or binding specificity within the synthesized core biology: LRP1 cell-surface/coated-pit/endosomal receptor biology, ligand and calcium binding, apolipoprotein/lipoprotein and alpha-2-macroglobulin cargo recognition, receptor-mediated endocytosis, transcytosis, phagocytic/lysosomal clearance, and Alzheimer-relevant amyloid-beta/tau handling.
Reason: For GO:0034185 (apolipoprotein binding), the IPI annotation with qualifier enables from PMID:18635818 is consistent with LRP1's core role in LDLR-family ligand binding and receptor-mediated internalization/clearance of lipoprotein, apolipoprotein, protease-inhibitor, amyloid-beta, tau, and other cargo complexes.

MARK AS OVER ANNOTATED
Summary: signaling receptor activity is marked over-annotated for LRP1 because this molecular-function term is too generic, interaction-map-like, or weakly informative relative to the gene-specific biology: LRP1 cell-surface/coated-pit/endosomal receptor biology, ligand and calcium binding, apolipoprotein/lipoprotein and alpha-2-macroglobulin cargo recognition, receptor-mediated endocytosis, transcytosis, phagocytic/lysosomal clearance, and Alzheimer-relevant amyloid-beta/tau handling.
Reason: For GO:0038023 (signaling receptor activity), the TAS annotation with qualifier enables from PMID:10880251 may reflect a real assay result or interaction, but this GO term does not identify the specific receptor, ligand-binding, cargo-clearance, endocytic, or localization annotation that explains LRP1's role in LDLR-family ligand binding and receptor-mediated internalization/clearance of lipoprotein, apolipoprotein, protease-inhibitor, amyloid-beta, tau, and other cargo complexes. More informative gene-specific annotations are present, so this is marked over-annotated rather than accepted as a core function.

Suggested Questions for Experts

Q: Which Alzheimer-relevant LRP1 effects are mediated by direct amyloid-beta/tau uptake versus indirect APOE/lipoprotein, vascular, or inflammatory pathways?

Q: Can tau/MAPT receptor activity and tau transcytosis/spread be represented with more specific GO terms than the current LRP1 GOA annotation set provides?

Q: Which LRP1 ligand classes should be prioritized as core in brain cell types: APOE lipoproteins, amyloid-beta species, tau, protease-inhibitor complexes, or extracellular-matrix-associated ligands?

Suggested Experiments

Experiment: Perturb LRP1 in human iPSC-derived endothelial cells, pericytes, astrocytes, microglia, and neurons, then separately measure APOE-lipoprotein uptake, amyloid-beta binding/clearance/transcytosis, tau uptake/spread, endosomal routing, and lysosomal degradation.

Hypothesis: LRP1 Alzheimer risk biology depends on cell-type-specific handling of amyloid-beta and tau cargo at vascular and glial barriers.

Type: cell-type-specific receptor-cargo trafficking assay

Experiment: Use endogenous motif-edited LRP1 constructs affecting NPXY/adaptor binding and regulated intramembrane cleavage to compare receptor internalization, cargo-specific uptake, intracellular-domain nuclear/cytoplasmic signaling, and downstream inflammatory or ECM responses.

Hypothesis: The LRP1 intracellular domain and adaptor-binding motifs tune cargo endocytosis versus signaling outputs.

Type: endogenous receptor motif rescue assay
