Descriptions

ARHGAP45 contains a GTPase activator for the Rho-type GTPase (RhoGAP) domain that would be able to negatively regulate the actin cytoskeleton as well as cell spreading. The N-terminal BAR domain of human ARHGAP45(Q92619) is autoinhibitory as ARHGAP45 mutants lacking this region, but not full-length ARHGAP45, show GAP activity towards RhoGTPases.

metal ion binding Binding to a metal ion.

1 GO annotations of biological process

Name Definition
intracellular signal transduction The process in which a signal is passed on to downstream components within the cell, which become activated themselves to further propagate the signal and finally trigger a change in the function or state of the cell.
