General description

Target of rapamycin complex 2 subunit MAPKAP1 (UniProt Q9BPZ7; also known as MEKK2-interacting protein 1, Mitogen-activated protein kinase 2-associated protein 1, mSIN1, Ras inhibitor MGC2745, SAPK-interacting protein 1, Stress-activated protein kinase-interacting 1, Stress-activated map kinase-interacting protein 1,, TORC2 subunit MAPKAP1) is encoded by the MAPKAP1 (also known as JC310, MIP1 SIN1, SIN1b, SIN1g) gene (Gene ID 79109) in human. mSIN1 is an essential component of the Torc2 complex. mTORC2 is comprised of mTOR, a large Ser/Thr protein kinase, along with mSIN1, GbL (mLST8), Protor1, Protor2, and Rictor. The mTORC2 complex 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 known to affect cytoskeletal organization and cell migration by exerting its effects through Rac, Rho, and PKC. mSIN1 is also known to directly interact with Ras, SPAKs, and JNK.

Myoblast fusion is essential for muscle development and regeneration. Yet, it remains poorly understood how mononucleated myoblasts fuse with preexisting fibers. We demonstrate that ERK1/2 inhibition (ERKi) induces robust differentiation and fusion of primary mouse myoblasts through a linear pathway
