Anti-Sin1 Antibody, clone 1C7.2

Sin1 (stress-activated protein kinase (SAPK)-interacting protein 1, MAPKAP1) is an essential component of the Torc2 complex. mTORC2 is comprised of mTOR, a large Ser/Thr protein kinase along with Sin1, GL (mLST8), Protor1, Protor2, and Rictor. The complex that is activated primarily downstream of PI3 Kinase and is known to affect cell proliferation and survival primarily by phosphorylating Akt on Ser473. Additionally, the mTORC2 complex is also known to effect cytoskeletal organization and migration by exerting its effects through Rac, Rho, and PKC. Sin1 is also known to directly interact without proteins that include Ras, SPAKs, and JNK.Sin1 is known to have multiple alternative splicing isoforms. Full-length Sin1 is a 522aa protein (59kDa). Sin1 (Isoform 5) (36 kDa) has exon 6 spliced to an alternative exon 7a that results in the loss of both the RBD and PHL domains. Sin1Isoform 2) (55 kDa) lacks exon 7 and lacks the RBD. Sin1 (Isoform 3) (53 kDa) lacks exon 8 lacks the PHL domain. Sin1 (Isoform 4) (37 kDa) lacks exon 1.
