The product of this gene belongs to the phosphatase 2A regulatory subunit B family. Protein phosphatase 2A 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 B regulatory subunit might modulate substrate selectivity and catalytic activity. This gene encodes a delta isoform of the regulatory subunit B56 subfamily. Alternatively spliced transcript variants encoding different isoforms have been identified. [provided by RefSeq, Jul 2008]
Forensic Context
A study in zebrafish demonstrated that the PPP2R5D transcript, a serine/threonine-protein phosphatase 2A regulatory subunit, increased in abundance postmortem and was functionally categorized among cancer-related genes [Pozhitkov et al. DOI:10.1098/rsob.160267].
