Ppp1r9b Gene Summary [Mouse]

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, Jul 2025]
