Gene Description

Agtr1a encodes the mouse angiotensin II type 1A receptor, a rhodopsin-family GPCR for angiotensin II. The receptor signals mainly through Gq/phospholipase C and calcium mobilization at the plasma membrane and mediates major renin-angiotensin outputs including vasoconstriction, renal sodium/water handling, aldosterone regulation, and blood-pressure control.

GO:0006954 inflammatory response
IBA
GO_REF:0000033
MARK AS OVER ANNOTATED
Summary: inflammatory response is a broad downstream phenotype and is not directly established as an Agtr1a-specific annotation by the reviewed evidence.
Reason: The curated model is better captured by AT1A receptor activity, angiotensin-activated PLC/calcium signaling, and renal/vascular blood-pressure terms rather than a generic inflammatory-response transfer.
Propagation Review
Root cause: TERM SCOPING PROBLEM
Failure modes: ROLE CONFLATION
Sources checked:
PANTHER:PTN002796070 SUPPORTS TRANSFER
The node is absent from the local PANTHER PAINT cache, so its full IBD seed set could not be inspected; the GOA WITH/FROM lists only the two mouse type-1 angiotensin II receptors, and UniProt classifies the target as PTHR10489:SF956 "TYPE-1 ANGIOTENSIN II RECEPTOR A". Descent of the target from an AT1-receptor node is therefore not in question - the issue is the term chosen, not the node placement.
MGI:MGI:87964 Β· mouse Agtr1a (the review target itself) SUPPORTS TRANSFER
The target's own MGI record is one of the two AT1-receptor IBD seeds, so the self-seed marks node membership. It does NOT mark independent experimental grounding here: Agtr1a's own IGI at this same term (GO:0006954, PMID:19404405) is itself reviewed as unsupported in this file, because that study shows the inflammatory effect is preserved when Ang II receptors are absent. Citing it as grounding would lean on an annotation this review removes.
MGI:MGI:87965 Β· mouse Agtr1b (angiotensin II receptor, type 1b) SUPPORTS TRANSFER
The closest mouse paralog and the only other seed; AT1a and AT1b share AT1 pharmacology, so transfer between them is sound. What is over-scoped is the term: inflammatory response names a downstream tissue-level consequence of AT1 signalling rather than the receptor's own step in it, which is captured by the angiotensin-activated PLC/calcium and blood-pressure terms retained elsewhere in this review.
Supporting Evidence:

GO:0046982 protein heterodimerization activity
ISO
GO_REF:0000119
MARK AS OVER ANNOTATED
Summary: protein heterodimerization activity is related to reported Agtr1a biology only as a broad downstream readout or generic interaction term.
Reason: This overstates the direct role of the gene product; the curated model is better captured by the specific receptor/ligand, pathway, and supported non-core phenotype terms.
Supporting Evidence:

Curation judgment: terms that describe broad responses to hormones, salt, activity, estrogen, corticosterone, dexamethasone, or generic cell proliferation/inflammation are generally downstream, context-specific phenotypes of angiotensin signaling.

ISO
GO_REF:0000096
KEEP AS NON CORE
Summary: recycling endosome is supported for Agtr1a in a tissue, developmental, trafficking, or disease-model context, but it is not the core molecular role.
Reason: This annotation captures a real downstream or context-specific consequence of Agtr1a activity. It should be retained as non-core so it does not obscure the primary receptor/ligand signaling function.
Supporting Evidence:

Trafficking and protein-interaction evidence: ATRAP was isolated using the cytoplasmic domain of murine AT1A and "interacts specifically with the carboxyl-terminal domain of the AT1a receptor"; overexpression inhibits AT1A-mediated PLC activation.

GO:0086097 phospholipase C-activating angiotensin-activated signaling pathway

GO_REF:0000119
ACCEPT
Summary: phospholipase C-activating angiotensin-activated signaling pathway is biologically consistent with the curated synthesis for Agtr1a and is supported by ISO evidence (GO_REF:0000119).
Reason: The term matches a direct molecular function, pathway, or location/physiological output of Agtr1a; it is specific enough to retain without replacement.
Supporting Evidence:

Core signaling: UniProt states that activated AGTR1A "couples to G-alpha proteins G(q) (GNAQ, GNA11, GNA14 or GNA15) and thus activates phospholipase C and increases the cytosolic Ca(2+) concentrations."

Core signaling: UniProt states that activated AGTR1A "couples to G-alpha proteins G(q) (GNAQ, GNA11, GNA14 or GNA15) and thus activates phospholipase C and increases the cytosolic Ca(2+) concentrations."

Core Functions

AGTR1A binds angiotensin II as a type 1 angiotensin receptor at the plasma membrane and activates Gq/phospholipase C/calcium signaling that underlies renin-angiotensin control of vasoconstriction, renal output, aldosterone production, and blood pressure.

Suggested Questions for Experts

Q: Which mouse AGTR1A signaling outputs should be represented as direct receptor signaling annotations rather than downstream organismal blood-pressure or kidney phenotypes?

Suggested Experiments

Experiment: Measure Ang II-induced PLC activation, calcium mobilization, and ERK/Rho pathway activation in Agtr1a-null and rescued mouse cells, including antagonist controls and Agtr1b comparison.

Hypothesis: The clearest direct AGTR1A pathway annotation is Gq/PLC/calcium signaling downstream of angiotensin II.

Type: cell signaling rescue assay
