These 3 proteins share 85% sequence identity. RhoA is the more extensively studied among these three. RhoA regulates a signal transduction pathway linking plasma membrane receptors to the assembly of focal adhesions and actin stress fibers. A number of proteins have been identified as targets of RhoA. Disease Mutations in RhoA were identified in diffuse gastric cancer. Relevance RhoA is thought to be important in mediating vasoconstriction in the penis.
