Gene Description

BACE1 encodes beta-secretase 1, a single-pass type I membrane aspartyl endopeptidase that initiates amyloidogenic processing of amyloid precursor protein. BACE1 cleaves APP at the beta-secretase site to generate soluble beta-cleaved APP and the membrane C-terminal fragment that is subsequently processed by gamma-secretase to produce amyloid-beta peptides. The enzyme is enriched in the trans-Golgi network and endosomal trafficking system, with pools at the cell surface, plasma membrane, recycling endosomes, late endosomes, and lysosomes; sorting through these compartments strongly controls access to APP and BACE1 degradation. BACE1 also cleaves other neuronal membrane substrates, contributing to synaptic, axonal, sensory, and behavioral phenotypes that are downstream of its protease and trafficking biology.

Summary: protein binding is marked over-annotated for BACE1 because this molecular-function term is too generic, interaction-map-like, or weakly informative relative to the gene-specific biology: BACE1 beta-secretase/aspartyl endopeptidase activity, amyloidogenic APP processing, membrane-substrate proteolysis, and TGN/endosomal trafficking that controls substrate access and enzyme turnover.
Reason: For GO:0005515 (protein binding), the IPI annotation with qualifier enables from PMID:30538620 may reflect a real assay result or interaction, but this GO term does not identify the specific protease, APP-processing, substrate-processing, or trafficking/localization annotation that explains BACE1's role in membrane aspartyl endopeptidase activity that initiates beta-site APP cleavage in TGN/endosomal trafficking compartments. More informative gene-specific annotations are present, so this is marked over-annotated rather than accepted as a core function.

This action keeps the term because it provides a specific, evidence-backed protease, APP-processing, substrate-processing, or trafficking/localization annotation rather than only a downstream phenotype or generic interaction label.

KEEP AS NON CORE
Summary: protein serine/threonine kinase binding is retained as a non-core molecular-function annotation for BACE1; it records a supported context, interaction, localization, or pathway branch that is secondary to BACE1 beta-secretase/aspartyl endopeptidase activity, amyloidogenic APP processing, membrane-substrate proteolysis, and TGN/endosomal trafficking that controls substrate access and enzyme turnover.
Reason: For GO:0120283 (protein serine/threonine kinase binding), the IPI annotation with qualifier enables from PMID:24305806 supports retaining the annotation, but the term describes a context-specific outcome or peripheral branch rather than the principal BACE1 function: membrane aspartyl endopeptidase activity that initiates beta-site APP cleavage in TGN/endosomal trafficking compartments. Keeping it as non-core prevents broad pathway participation from being promoted to core function.
GO:1990000 amyloid fibril formation

MODIFY
Summary: amyloid fibril formation is directionally related to BACE1 biology but is not the best curation target; amyloid-beta formation, amyloid precursor protein catabolic process better captures the specific supported function or process.
Reason: For GO:1990000 (amyloid fibril formation), the TAS annotation with qualifier involved_in from Reactome:R-HSA-977225 supports a relationship to BACE1, but the current term is less precise than amyloid-beta formation, amyloid precursor protein catabolic process for the evidence and for the synthesized core/non-core role of BACE1. The MODIFY action preserves the biological intent while pointing curators to the more informative GO term.

MARK AS OVER ANNOTATED
Summary: protein binding is marked over-annotated for BACE1 because this molecular-function term is too generic, interaction-map-like, or weakly informative relative to the gene-specific biology: BACE1 beta-secretase/aspartyl endopeptidase activity, amyloidogenic APP processing, membrane-substrate proteolysis, and TGN/endosomal trafficking that controls substrate access and enzyme turnover.
Reason: For GO:0005515 (protein binding), the IPI annotation with qualifier enables from PMID:15286784 may reflect a real assay result or interaction, but this GO term does not identify the specific protease, APP-processing, substrate-processing, or trafficking/localization annotation that explains BACE1's role in membrane aspartyl endopeptidase activity that initiates beta-site APP cleavage in TGN/endosomal trafficking compartments. More informative gene-specific annotations are present, so this is marked over-annotated rather than accepted as a core function.

Summary: proteolysis is retained as a core biological-process annotation for BACE1; it captures process participation within the synthesized core biology: BACE1 beta-secretase/aspartyl endopeptidase activity, amyloidogenic APP processing, membrane-substrate proteolysis, and TGN/endosomal trafficking that controls substrate access and enzyme turnover.
Reason: For GO:0006508 (proteolysis), the IDA annotation with qualifier involved_in from PMID:10677483 is consistent with BACE1's core role in membrane aspartyl endopeptidase activity that initiates beta-site APP cleavage in TGN/endosomal trafficking compartments. This action keeps the term because it provides a specific, evidence-backed protease, APP-processing, substrate-processing, or trafficking/localization annotation rather than only a downstream phenotype or generic interaction label.

KEEP AS NON CORE
Summary: positive regulation of neuron apoptotic process is retained as a non-core biological-process annotation for BACE1; it records a supported context, interaction, localization, or pathway branch that is secondary to BACE1 beta-secretase/aspartyl endopeptidase activity, amyloidogenic APP processing, membrane-substrate proteolysis, and TGN/endosomal trafficking that controls substrate access and enzyme turnover.
Reason: For GO:0043525 (positive regulation of neuron apoptotic process), the IGI annotation with qualifier involved_in from PMID:29371969 supports retaining the annotation, but the term describes a context-specific outcome or peripheral branch rather than the principal BACE1 function: membrane aspartyl endopeptidase activity that initiates beta-site APP cleavage in TGN/endosomal trafficking compartments. Keeping it as non-core prevents broad pathway participation from being promoted to core function.

MARK AS OVER ANNOTATED
Summary: protein binding is marked over-annotated for BACE1 because this molecular-function term is too generic, interaction-map-like, or weakly informative relative to the gene-specific biology: BACE1 beta-secretase/aspartyl endopeptidase activity, amyloidogenic APP processing, membrane-substrate proteolysis, and TGN/endosomal trafficking that controls substrate access and enzyme turnover.
Reason: For GO:0005515 (protein binding), the IPI annotation with qualifier enables from PMID:27179792 may reflect a real assay result or interaction, but this GO term does not identify the specific protease, APP-processing, substrate-processing, or trafficking/localization annotation that explains BACE1's role in membrane aspartyl endopeptidase activity that initiates beta-site APP cleavage in TGN/endosomal trafficking compartments. More informative gene-specific annotations are present, so this is marked over-annotated rather than accepted as a core function.

Reason: For GO:0005794 (Golgi apparatus), the IDA annotation with qualifier located_in from PMID:10531052 is consistent with BACE1's core role in membrane aspartyl endopeptidase activity that initiates beta-site APP cleavage in TGN/endosomal trafficking compartments. This action keeps the term because it provides a specific, evidence-backed protease, APP-processing, substrate-processing, or trafficking/localization annotation rather than only a downstream phenotype or generic interaction label.

Core Functions

BACE1 is the membrane beta-secretase/aspartyl endopeptidase that cleaves APP at the beta-secretase site, initiating amyloidogenic APP processing and amyloid-beta production. Its access to APP is controlled by TGN, endosomal, recycling-endosomal, cell-surface, and lysosomal trafficking.

Supporting Evidence:
  • PMID:10531052
    Overexpression of this protease, termed BACE (for beta-site APP-cleaving enzyme) increased the amount of beta-secretase cleavage products
  • PMID:10677483
    memapsin 2 cleaved the beta-secretase site of APP
  • PMID:10677483
    catalyzes the rate-limiting step of the in vivo production of the beta-amyloid (Abeta) peptide
  • PMID:15886016
    GGA1 regulates the retrograde transport of internalized BACE1 from endosomal compartments to the TGN
  • PMID:20354142
    SNX6 negatively modulates BACE1-mediated cleavage of APP
  • file:human/BACE1/BACE1-deep-research-falcon.md
    This amyloidolytic activity represents a clearance mechanism for toxic AΞ² species, and the BACE1/APP ratio appears to be a primary determinant of the balance between amyloidogenic and amyloidolytic activities

Suggested Questions for Experts

Q: Which non-APP BACE1 substrates should be treated as core physiological BACE1 biology rather than downstream neuronal phenotypes?

Suggested experts: BACE1 substrate experts, GO protease curators

Q: How should BACE1 trafficking annotations distinguish compartments that control APP access from compartments involved mainly in BACE1 degradation?

Suggested experts: endosomal trafficking experts, APP processing experts

Q: Should BACE1's amyloidolytic cleavage of Abeta40/42 at the beta-34 site (generating non-toxic Abeta34) be captured distinctly from its amyloidogenic beta-site APP cleavage, given that the BACE1/APP ratio sets the balance between the two activities?

Suggested experts: amyloid-beta metabolism experts, GO protease curators

Suggested Experiments

Experiment: Use endogenous BACE1 tagging and APP cleavage reporters to quantify beta-secretase activity after perturbing GGA, SNX6, BIN1, USP8, and lysosomal-routing pathways.

Hypothesis: BACE1 amyloidogenic output is controlled primarily by compartmental access to APP rather than total BACE1 abundance alone.

Type: compartment-resolved APP beta-cleavage assay

Experiment: Compare APP, CHL1, neuregulin, SEZ6-family, and other neuronal substrates in BACE1 wild-type and active-site mutant human neurons.

Hypothesis: Non-APP synaptic and behavioral phenotypes arise from distinct substrate classes but share the same aspartyl endopeptidase activity.

Type: multi-substrate protease activity assay
