products description :
PPP1R14A (Protein phosphatase 1 regulatory subunit 14A) is a phosphorylation-dependent inhibitory protein for smooth muscle myosin phosphate. Myosin phosphatase can reverse MYL (myosin light chain) phosphorylation to induce a state of relaxation. However, during agonist-induced contraction at constant Ca2+ concurrent inhibition of myosin phosphatase leads to increases in MYL phosphorylation and tension. These calcium-independent increases in myosin phosphorylation and tension are termed calcium sensitization.

ncbi summary :
The protein encoded by this gene belongs to the protein phosphatase 1 (PP1) inhibitor family. This protein is an inhibitor of smooth muscle myosin phosphatase, and has higher inhibitory activity when phosphorylated. Inhibition of myosin phosphatase leads to increased myosin phosphorylation and enhanced smooth muscle contraction. Alternatively spliced transcript variants encoding different isoforms have been noted for this gene. [provided by RefSeq, Sep 2011]
uniprot summary :
PPP1R14A: a phosphorylation-dependent inhibitory subunit of protein phosphatase 1 (PP-1A). Phosphorylation by PKC regulates its binding to PP-1A. Acts co-operatively to inhibit myosin light chain phosphatase (MLCP) activity. Inhibition leads to increased myosin phosphorylation and enhances smooth muscle contraction in the absence of increased intracellular Ca(2 ) concentration. Involved in the regulation of cell morphology, re-organisation of microfilaments, and cell spreading. Also expressed in human platelets and in brain where it may play a role in cerebellar long-term synaptic depression. Phosphorylation by ILK or Rho kinase enhances its ability to inhibit PP-1A. Protein type: Inhibitor; Protein phosphatase, regulatory subunit. Chromosomal Location of Human Ortholog: 19q13.1. Cellular Component: cytoplasm. Molecular Function: protein phosphatase inhibitor activity. Biological Process: regulation of phosphorylation; negative regulation of catalytic activity
