Rho GTPase activating protein

Function

Rho GTPase activating protein (RhoGAP) are one of the main classes of Rho GTPase regulators that are crucial in cell cytoskeletal organization, growth, differentiation, neuronal development and synaptic functions[1]. RhoGAPs contain a RhoGAP domain.

Relevance

RhoGAPs are present in altered abundance in a variety of human cancers and may serve as targets for cancer therapy[2].
