MGI Phenotype

FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] Rho GTPase activating protein 5 negatively regulates RHO GTPases, a family which may mediate cytoskeleton changes by stimulating the hydrolysis of bound GTP. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]
PHENOTYPE: Homozygotes die at birth, are 30% smaller, do not inflate their lungs, and show a small thymus, abnormal adipocyte differentiation and brain defects in the corpus callosum, anterior commissure and lateral ventricles. Mutant MEFs show impaired adipogenesis but undergo myogenesis in response to IGF-1. [provided by MGI curators]

Nature of Mutation

Two transcripts of the Arhgap5 gene are displayed on Ensembl.

Protein Function and Prediction

The Arhgap5 gene encodes a 1503 amino acid GTPase-activating protein for Rho family members. The protein contains 4 FF domains, and a Rho-GAP domain at residues 1261-1448 (Uniprot P97393). Arhgap5 (alternatively, p190B) is a cytosolic Rho family GTPase-activating protein that is co-localized with the alpha 5 beta 1 integrin receptor for fibronectin in fibrillar patterns (1;2). P190B functions to regulate actin stress fiber dynamics through the hydrolysis of Rho-GTP (2-4). Through its function in hydrolyzing Rho-GTP, p190B also regulates cell cycle progression (3). The GAP domain is crucial for the regulation of actin cytoskeletal rearrangements in axonal pathfinding and stability (5-8) and in response to integrin engagement (9;10), growth factor stimulation (4), and v-Src transformation (11). When p190B heterozygous mice mated to a MMTV-Neu breast cancer model, tumor penetrance was reduced and tumor onset was delayed (12). Further studies determined that p190B regulates chromosome segregation and apoptosis in cancer cells (13).

Expression/Localization

p190B localizes to centrosomes during interphase and mitosis (13).

Background

Arhgap5^{tm1Jset/tm1Jset}; MGI:2179998

involves: 129S2/SvPas * C57BL/6J

Homozygotes die at birth, are 30% smaller, do not inflate their lungs, and show a small thymus, abnormal adipocyte differentiation and brain defects in the corpus callosum, anterior commissure and lateral ventricles (14). Mutant MEFs show impaired adipogenesis but undergo myogenesis in response to IGF-1 (14). Also depletion in Arhgap5 leads to decreased incidence of mammary ductal morphogenesis (15).
