Protein

Serine/threonine-protein phosphatase PP1-beta catalytic subunit

Gene

ppp1cb

Organism
Xenopus tropicalis (Western clawed frog) (Silurana tropicalis)
Status
Reviewed - Annotation score: 3 out of 5- Experimental evidence at transcript leveli

Functioni

Protein phosphatase that associates with over 200 regulatory proteins to form highly specific holoenzymes which dephosphorylate hundreds of biological targets. Protein phosphatase (PP1) is essential for cell division, it participates in the regulation of glycogen metabolism, muscle contractility and protein synthesis. Involved in regulation of ionic conductances and long-term synaptic plasticity (By similarity).By similarity

Catalytic activityi

[a protein]-serine/threonine phosphate + H2O = [a protein]-serine/threonine + phosphate.

Cofactori

Binds 2 manganese ions per subunit.By similarity
