    Summary
    Predicted to enable several functions, including [phosphorylase] phosphatase activity; glycogen binding activity; and protein phosphatase 1 binding activity. Predicted to contribute to phosphoprotein phosphatase activity. Involved in positive regulation of glycogen biosynthetic process. Predicted to be located in glycogen granule. Predicted to be part of protein phosphatase type 1 complex. Is expressed in several structures, including alimentary system; genitourinary system; hemolymphoid system gland; respiratory system; and sensory organ. Orthologous to human PPP1R3B (protein phosphatase 1 regulatory subunit 3B). [provided by Alliance of Genome Resources, Dec 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.
