Summary: Predicted to enable several functions, including D2 dopamine receptor binding activity; enzyme binding activity; and transmembrane transporter binding activity. Involved in cellular response to morphine; regulation of opioid receptor signaling pathway; and regulation of postsynapse assembly. Acts upstream of or within several processes, including actin filament organization; calcium-mediated signaling; and dendrite development. Located in cortical actin cytoskeleton and filopodium. Is expressed in several structures, including alimentary system; brain; connective tissue; genitourinary system; and hemolymphoid system. Orthologous to human PPP1R9B (protein phosphatase 1 regulatory subunit 9B). [provided by Alliance of Genome Resources, Nov 2024]

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.
