Summary
Predicted to enable protein phosphatase regulator activity. Predicted to be involved in apoptotic process involved in morphogenesis; positive regulation of extrinsic apoptotic signaling pathway in absence of ligand; and protein dephosphorylation. Is active in glutamatergic synapse. Is expressed in several structures, including cerebral cortex; eye; genitourinary system; thymus primordium; and tooth. Orthologous to human PPP2R1B (protein phosphatase 2 scaffold subunit Abeta). [provided by Alliance of Genome Resources, Apr 2022]

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.
