Summary: This gene encodes a bifunctional signal transduction molecule. Dopaminergic and glutamatergic receptor stimulation regulates its phosphorylation and function as a kinase or phosphatase inhibitor. As a target for dopamine, this gene may serve as a therapeutic target for neurologic and psychiatric disorders in humans. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Sep 2015]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.

NM_001313970.1 → NP_001300899.1 protein phosphatase 1 regulatory subunit 1B isoform 2

Status: REVIEWED

Description

Transcript Variant: This variant (2) uses an alternate exon in place of the first exon compared to variant 1.This difference causes translation initiation at a downstream AUG and results in an isoform (2) with a shorter N-terminus compared to isoform 1.
