StorageMaintain refrigerated at 2-8°C for up to 6 months. For long term storage store at -20°C in small aliquots to prevent freeze-thaw cycles.
PrecautionsMYPT1 Antibody (N-term) is for research use only and not for use in diagnostic or therapeutic procedures.
Protein Information
Name PPP1R12A (HGNC:7618)
Function Key regulator of protein phosphatase 1C (PPP1C). Mediates binding to myosin. As part of the PPP1C complex, involved in dephosphorylation of PLK1. Capable of inhibiting HIF1AN- dependent suppression of HIF1A activity.
Cellular Location Cytoplasm. Note=Along actomyosin filaments and stress fibers
Tissue Location Expressed in striated muscles, specifically in type 2a fibers (at protein level).

The major protein phosphatase-1 (PP1) is composed of 3 subunits with apparent molecular mass of 110-130, 37 & 20 kDa. The 110-130 kDa component act as a regulatory subunit known as myosin binding (MBS) or myosin phosphatase targeting subunit (MYPT). The N-terminal portion of MYPT binds to both PP1c-delta and phosphorylated myosin, thereby increasing myosin phosphatase activity. Two isoforms of MYPT have been identified (MYPT1 & MYPT2) and share 61% sequence identity. While MYPT1 is widely distributed in human tissues, MYPT2 is mostly detected in brain and heart.
