>cd04141 Rit_Rin_Ric Rit/Rin/Ric subfamily. Rit (Ras-like protein in all tissues), Rin (Ras-like protein in neurons) and Ric (Ras-related protein which interacts with calmodulin) form a subfamily with several unique structural and functional characteristics. These proteins all lack a the C-terminal CaaX lipid-binding motif typical of Ras family proteins, and Rin and Ric contain calmodulin-binding domains. Rin, which is expressed only in neurons, induces neurite outgrowth in rat pheochromocytoma cells through its association with calmodulin and its activation of endogenous Rac/cdc42. Rit, which is ubiquitously expressed in mammals, inhibits growth-factor withdrawl-mediated apoptosis and induces neurite extension in pheochromocytoma cells. Rit and Rin are both able to form a ternary complex with PAR6, a cell polarity-regulating protein, and Rac/cdc42. This ternary complex is proposed to have physiological function in processes such as tumorigenesis. Activated Ric is likely to sign
