Rac GTPase-activating protein 1 is an enzyme that in humans is encoded by the RACGAP1 gene.^[5]

Function

Rho GTPases control a variety of cellular processes. There are 3 subtypes of Rho GTPases in the Ras superfamily of small G proteins: RHO (see MIM 165370), RAC (see RAC1; MIM 602048), and CDC42 (MIM 116952). GTPase-activating proteins (GAPs) bind activated forms of Rho GTPases and stimulate GTP hydrolysis. Through this catalytic function, Rho GAPs negatively regulate Rho-mediated signals. GAPs may also serve as effector molecules and play a role in signaling downstream of Rho and other Ras-like GTPases.[supplied by OMIM]^[6]

Interactions

RACGAP1 has been shown to interact with Rnd2^[7] and SLC26A8.^[8]

During cytokinesis, RACGAP1 has been shown to interact with KIF23 to form the centralspindlin complex.^[9] This complex is essential for the formation of the central spindle. RACGAP1 also interacts with PRC1 to stabilize and maintain the central spindle as anaphase proceeds.^[10]
