Predicted to enable protein phosphatase regulator activity. Predicted to be involved in protein dephosphorylation. [provided by Alliance of Genome Resources, Apr 2022]
Annotation information
Note: Although this gene was previously annotated as a protein-coding locus, it appears to be a pseudogene of PPP4R1 (GeneID: 9989) because the CDS is disrupted by a nonsense mutation that truncates the protein after 415-aa. Consequently, transcripts are candidates for nonsense-mediated decay (NMD). [13 Feb 2013]

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.
