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],[2]. RhoGAPs contain a RhoGAP domain.

  • RhoGAP7 activates the small GTPases RHOA, RHOB, RHOC and CDC42.
  • RhoGAP9 regulates adhesion of hematopoietic cells to the extracellular matrix.

Relevance

RhoGAPs are present in altered abundance in a variety of human cancers and may serve as targets for cancer therapy[3],[4]. RhoGAP10 variants may be associated with schizophrenia[5].
