General annotation (Comments)

Function	Plasma membrane-associated small GTPase which cycles between active GTP-bound and inactive GDP-bound states. In its active state, binds to a variety of effector proteins to regulate cellular responses such as secretory processes, phagocytosis of apoptotic cells, epithelial cell polarization and growth-factor induced formation of membrane ruffles.
Enzyme regulation	Regulated by guanine nucleotide exchange factors (GEFs) which promote the exchange of bound GDP for free GTP, GTPase activating proteins (GAPs) which increase the GTP hydrolysis activity, and GDP dissociation inhibitors which inhibit the dissociation of the nucleotide from the GTPase.
Subunit structure	Interacts with the GEF proteins PREX1, RASGRF2, DOCK1, DOCK2 and DOCK7, which promote the exchange between GDP and GTP, and therefore activate it. Interacts with PARD6A, PARD6B and PARD6G in a GTP-dependent manner. Part of a quaternary complex containing PARD3, some PARD6 protein (PARD6A, PARD6B or PARD6G) and some atypical PKC protein (PRKCI or PRKCZ), which plays a central role in epithelial cell polarization. Found in a trimeric complex composed of DOCK1 and ELMO1, which plays a central role in phagocytosis of apoptotic cells. Interacts with RALBP1 via its effector domain. Interacts with BAIAP2, BAIAP2L1, PLXNB1, CYFIP1/SRA-1 and DEF6. Interacts with NOXA1. Interacts with ARHGEF2 By similarity. Part of a complex with MAP2K3, MAP3K3 and CCM2. Interacts with NISCH. Ref.4 Ref.5 Ref.6 Ref.7 Ref.8
Subcellular location	Cell membrane; Lipid-anchor; Cytoplasmic side By similarity. Melanosome By similarity. Note: Inner surface of plasma membrane possibly with attachment requiring prenylation of the C-terminal cysteine By similarity.
Tissue specificity	Widely expressed. Ref.1
Domain	The effector region mediates interaction with DEF6 By similarity.
Sequence similarities	Belongs to the small GTPase superfamily. Rho family.
