Function

edit

ARHGEF9 belongs to a family of Rho-like GTPases that act as molecular switches by cycling from the active GTP-bound state to the inactive GDP-bound state. These proteins are key regulators of the actin cytoskeleton and are involved in cell signaling.[supplied by OMIM][7]

Interactions

edit

ARHGEF9 has been shown to interact with GPHN[8] and SMURF1.[9]
