Aliases for RACGAP1 Gene
External Ids for RACGAP1 Gene
The protein encoded by this gene belongs to the GTPase-activating protein (GAP) family. GAPs bind activated forms of Rho GTPases and stimulate GTP hydrolysis. Through this catalytic function, GAPs negatively regulate Rho-mediated signals. This protein plays a regulatory role in initiation of cytokinesis, controlling cell growth and differentiation of hematopoietic cells, regulating spermatogenesis, and in neuronal proliferation. Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Sep 2011]
GeneCards Summary for RACGAP1 Gene
RACGAP1 (Rac GTPase Activating Protein 1) is a Protein Coding gene. Among its related pathways are Signaling by GPCR and Class I MHC mediated antigen processing and presentation. GO annotations related to this gene include protein kinase binding and GTPase activator activity. An important paralog of this gene is ABR.
UniProtKB/Swiss-Prot for RACGAP1 Gene
Component of the centralspindlin complex that serves as a microtubule-dependent and Rho-mediated signaling required for the myosin contractile ring formation during the cell cycle cytokinesis. Required for proper attachment of the midbody to the cell membrane during cytokinesis. Plays key roles in controlling cell growth and differentiation of hematopoietic cells through mechanisms other than regulating Rac GTPase activity. Also involved in the regulation of growth-related processes in adipocytes and myoblasts. May be involved in regulating spermatogenesis and in the RACGAP1 pathway in neuronal proliferation. Shows strong GAP (GTPase activation) activity towards CDC42 and RAC1 and less towards RHOA. Essential for the early stages of embryogenesis. May play a role in regulating cortical activity through RHOA during cytokinesis. May participate in the regulation of sulfate transport in male germ cells.
