Component of the membrane-bound TORC2 complex; binds to phosphoinositide-(4,5)-bisphosphate through the C-terminal PH domain, anchoring TORC2 to the plasma membrane; binds directly to Tor2p substrate and downstream TORC2 effector Ypk2p, through the conserved central CRIM domain; may function along with Tsc11p as a scaffold for integrity of the TORC2 complex; role in regulating actin organization and growth control; orthologous to human MAPKAP1/SIN1
