Previous GeneCards Identifiers for PPP2R1A Gene
This gene encodes a constant regulatory subunit of protein phosphatase 2. Protein phosphatase 2 is one of the four major Ser/Thr phosphatases, and it is implicated in the negative control of cell growth and division. It consists of a common heteromeric core enzyme, which is composed of a catalytic subunit and a constant regulatory subunit, that associates with a variety of regulatory subunits. The constant regulatory subunit A serves as a scaffolding molecule to coordinate the assembly of the catalytic subunit and a variable regulatory B subunit. This gene encodes an alpha isoform of the constant regulatory subunit A. Alternatively spliced transcript variants have been described. [provided by RefSeq, Apr 2010]
GeneCards Summary for PPP2R1A Gene
PPP2R1A (Protein Phosphatase 2 Scaffold Subunit Aalpha) is a Protein Coding gene. Diseases associated with PPP2R1A include Mental Retardation, Autosomal Dominant 36 and Endometrioid Ovary Carcinoma. Among its related pathways are CTLA4 Signaling and RET signaling. GO annotations related to this gene include protein heterodimerization activity and antigen binding.

UniProtKB/Swiss-Prot for PPP2R1A Gene
The PR65 subunit of protein phosphatase 2A serves as a scaffolding molecule to coordinate the assembly of the catalytic subunit and a variable regulatory B subunit. Required for proper chromosome segregation and for centromeric localization of SGO1 in mitosis.
Protein Ser/Thr phosphatases are a group of enzymes that catalyze the removal of phosphate groups from serine and/or threonine residues by hydrolysis of phosphoric acid monoesters. They oppose the action of kinases and phosphorylases and are involved in signal transduction.
