RHOA (human, P61586) curation notes
Deep research providers were unavailable in this environment; evidence below is from cached
publications and the UniProt record.
Localization (benchmark-relevant)
- RHOA is intracellular: UniProt
SUBCELLULAR LOCATION: Cell membrane; Lipid-anchor; Cytoplasmic
side. plus cytosol (RhoGDI-bound), cell cortex, cleavage furrow, midbody, apical junction complex
and postsynapse. It is not surface-exposed.
GO:0009898 cytoplasmic side of plasma membrane accepted as the most precise membrane term;
cytoplasm and cell periphery marked TOO_GENERAL; cytoskeleton modified to cell cortex +
cleavage furrow (RHOA regulates rather than constitutes the cytoskeleton).
- Equatorial cortex recruitment: UniProt "Translocates to the equatorial region before furrow
formation in a ECT2-dependent manner."
Core functions
- GTPase switch driving actomyosin contractility: "Regulates a signal transduction pathway linking
plasma membrane receptors to the assembly of focal adhesions and actin stress fibers".
- Cleavage furrow specification and cytokinesis: "Involved in a microtubule-dependent signal that
is required for the myosin contractile ring formation during cell cycle cytokinesis";
"Plays an essential role in cleavage furrow formation."
- Apical junction assembly in epithelia: "Required for the apical junction formation of
keratinocyte cell-cell adhesion".
- Postsynaptic actin remodelling retained as accepted process/location rows
PMID:21423166.
Review decisions
- 54 generic
GO:0005515 rows REMOVEd under the protein-binding policy; myosin binding and protein
kinase binding retained as informative.
GO:0090324 negative regulation of oxidative phosphorylation and GO:1903427 negative regulation
of ROS biosynthetic process marked over-annotated (electronically transferred, no mechanism).
- Numerous tissue/organismal outputs (bone, tooth, T-cell development, angiogenesis, valve
formation) kept as non-core.
