Summary: Predicted to enable several functions, including alpha-1,4-glucan glucosyltransferase (UDP-glucose donor) activity; phosphatase activity; and polysaccharide binding activity. Predicted to be involved in several processes, including carbohydrate phosphorylation; negative regulation of phosphatase activity; and peptidyl-tyrosine dephosphorylation. Predicted to act upstream of or within several processes, including glycogen biosynthetic process; regulation of protein localization; and regulation of protein metabolic process. Predicted to be located in several cellular components, including cytoplasmic side of rough endoplasmic reticulum membrane; dendrite; and perikaryon. Predicted to be active in cytosol and nucleus. Human ortholog(s) of this gene implicated in progressive myoclonus epilepsy. Orthologous to human EPM2A (EPM2A glucan phosphatase, laforin). [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.
