MeSH Heading: Protein Phosphatase 1
Tree Number(s): D08.811.277.352.650.625.687; D12.776.476.559.687
Unique ID: D054645
RDF Unique Identifier: http://id.nlm.nih.gov/mesh/D054645
Scope Note: A eukayrotic protein serine-threonine phosphatase subtype that dephosphorylates a wide variety of cellular proteins. The enzyme is comprised of a catalytic subunit and regulatory subunit. Several isoforms of the protein phosphatase catalytic subunit exist due to the presence of multiple genes and the alternative splicing of their mRNAs. A large number of proteins have been shown to act as regulatory subunits for this enzyme. Many of the regulatory subunits have additional cellular functions.
