RHOA

Ras homolog gene family, member A, also known as RHOA, is a human gene.

RhoA is a small GTPase protein known to regulate the actin cytoskeleton in the formation of stress fibers.

It acts upon two known effector proteins: ROCK1 (Rho-associated, coiled-coil containing protein kinase 1) and DIAPH1 (diaphanous homolog 1 (Drosophila)).

RhoA is part of a larger family of related proteins known as the Ras superfamily; proteins involved in the regulation and timing of cell division.
