Summary
Enables hydrolase activity, hydrolyzing N-glycosyl compounds and mannosidase activity. Predicted to be involved in N-glycan processing and protein deglycosylation. Predicted to be located in Golgi apparatus and membrane. Predicted to be integral component of membrane. Predicted to be active in Golgi membrane. Is expressed in olfactory epithelium; retina outer nuclear layer; skeletal muscle; and vomeronasal organ. Orthologous to human MAN2A2 (mannosidase alpha class 2A member 2).

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.
