SIN1 rabbit pAb

function:Essential component of the TORC2 complex, which plays a critical role in AKT1 'Ser-473' phosphorylation, and may modulate the phosphorylation of PKCA and regulate actin cytoskeleton organization. Inhibits MAP3K2 by preventing its dimerization and autophosphorylation. Inhibits HRAS and KRAs signaling. Enhances osmotic stress-induced phosphorylation of ATF2 and ATF2-mediated transcription.,similarity:Belongs to the SIN1 family.,subunit:All isoforms except isoform 4 are able to be part of the target of rapamycin 2 complex (TORC2) comprised of FRAP1, LST8, PROTOR1, RICTOR and MAPKAP1. Interacts with ATF2, MAP3K2 and MAPK8. Interacts with GTP-bound HRAS and KRAS. Interacts with IFNAR2.,tissue specificity:Ubiquitously expressed, with highest levels in heart and skeletal muscle.,
