Summaries for PPP1R8 Gene

Entrez Gene Summary for PPP1R8 Gene

  • This gene, through alternative splicing, encodes three different isoforms. Two of the protein isoforms encoded by this gene are specific inhibitors of type 1 serine/threonine protein phosphatases and can bind but not cleave RNA. The third protein isoform lacks the phosphatase inhibitory function but is a single-strand endoribonuclease comparable to RNase E of E. coli. This isoform requires magnesium for its function and cleaves specific sites in A+U-rich regions of RNA. [provided by RefSeq, Jul 2008]

GeneCards Summary for PPP1R8 Gene

PPP1R8 (Protein Phosphatase 1 Regulatory Subunit 8) is a Protein Coding gene. Among its related pathways are Activation of cAMP-Dependent PKA and Apoptotic Pathways in Synovial Fibroblasts. GO annotations related to this gene include RNA binding. An important paralog of this gene is SLC4A1AP.

UniProtKB/Swiss-Prot for PPP1R8 Gene

  • Inhibitor subunit of the major nuclear protein phosphatase-1 (PP-1). It has RNA-binding activity but does not cleave RNA and may target PP-1 to RNA-associated substrates. May also be involved in pre-mRNA splicing. Binds DNA and might act as a transcriptional repressor. Seems to be required for cell proliferation.

  • Isoform Gamma is a site-specific single-strand endoribonuclease that cleaves single strand RNA 3 to purines and pyrimidines in A+U-rich regions. It generates 5-phosphate termini at the site of cleavage. This isoform does not inhibit PP-1. May be implicated in mRNA splicing.
