Anti-phospho-Mypt1 (Ser507) Antibody

Myosin phosphatase targeting subunit 1 (MYPT1) is a regulatory targeting subunit that is thought to be responsible for targeting the holoenzyme to the proper positions in muscle and moving PP1 to myosin. MYPT1 is the major subunit involved in myosin light chain phosphatase (MLCP). It is also essential for vasodilation caused by nitric oxide (NO). A decrease in MYPT1 has been shown to play a role in increased tolerance of NO in pulmonary arteries.

~120 kDa observed.
Uniprot gives a calculated molecular weight of 115 kDa, which can be observed at higher molecular weights due to hyperphosphorylation. Uncharacterized bands appear at ~30 kDa and ~130 kDa in some lysates.

Epitope: Phosphorylated (Ser507)
