Protein Structure

UniProt Annotation

Function

Acts upstream of PAK1 to regulate the actin cytoskeleton, adhesion turnover and increase cell migration. Stimulates quiescent cells to reenter the cell cycle. Has no detectable GTPase activity but its high intrinsic guanine nucleotide exchange activity suggests it is constitutively GTP- bound. Plays a role in the regulation of cell morphology and cytoskeletal organization. Required in the control of cell shape (By similarity). {ECO:0000250}.

Subcellular Localization

Cell membrane {ECO:0000250UniProtKB:Q7L0Q8}; Lipid-anchor {ECO:0000250UniProtKB:Q7L0Q8}; Cytoplasmic side {ECO:0000250UniProtKB:Q7L0Q8}. Golgi apparatus membrane {ECO:0000250UniProtKB:Q7L0Q8}; Lipid-anchor {ECO:0000250UniProtKB:Q7L0Q8}. Cell junction, focal adhesion {ECO:0000250UniProtKB:Q7L0Q8}. Cell projection, podosome {ECO:0000250UniProtKB:Q7L0Q8}. Note=Localizes to podosomes in SRC-transformed cells. {ECO:0000250UniProtKB:Q7L0Q8}.
