PPP1CA

Serine/threonine-protein phosphatase PP1-alpha catalytic subunit is an is_associated_with::enzyme that in humans is encoded by the PPP1CA is_associated_with::gene.

Function
The protein encoded by this gene is one of the three catalytic subunits of is_associated_with::protein phosphatase 1 (PP1). PP1 is a serine/threonine specific protein phosphatase known to be involved in the regulation of a variety of cellular processes, such as cell division, glycogen metabolism, muscle contractility, protein synthesis, and HIV-1 viral transcription. Increased PP1 activity has been observed in the end stage of heart failure. Studies in both human and mice suggest that PP1 is an important regulator of cardiac function. Mouse studies also suggest that PP1 functions as a suppressor of learning and memory. Three alternatively spliced transcript variants encoding different isoforms have been found for this gene.
