Supplementary information

Myosin Phosphatase also known as Myosin Light Chain Phosphatase is a critical enzyme involved in muscle contraction regulation. It has no specific subunit weight assigned to it but the holoenzyme usually consists of three subunits: a catalytic subunit (PP1c) a large regulatory subunit (MYPT1) and a small regulatory subunit (M20). Myosin Phosphatase is expressed in smooth muscle and non-muscle tissues where it plays a role in the relaxation phase of muscle contraction.
Biological function summary

Myosin Phosphatase functions by dephosphorylating myosin light chains which leads to muscle relaxation. It is an essential component of the Myosin Phosphatase holoenzyme complex which ensures smooth muscle function. Through its activity this enzyme influences processes such as cell motility cell division and vascular tone maintenance. Its activity is regulated by signals that affect the phosphorylation state of its target substrates.

Pathways

Myosin Phosphatase is a critical player in the Rho/Rhokinase signaling pathways. It participates in the regulation of cellular contraction and cytoskeletal dynamics. Within these pathways it interacts closely with Rho-associated protein kinase (ROCK) which can inhibit Myosin Phosphatase activity by phosphorylating the MYPT1 subunit. This pathway influence extends to its interactions with other proteins like Cdc42 and Rac which participate in similar cellular functions.

Myosin Phosphatase is linked to hypertension and asthma. Dysregulation of Myosin Phosphatase activity can result in altered muscle tone and has implications in abnormal vascular smooth muscle contraction contributing to high blood pressure. In asthma abnormal airway smooth muscle contractions lead to bronchoconstriction further supported by its interaction with proteins such as ROCK and myosin light chain kinase (MLCK) both involved in similar disease-related pathways.
