Anti-GLMP antibodies are used in the immunodetection of the protein glycosylated lysosomal membrane protein. In humans, the canonical protein has a reported length of 406 amino acid residues and a mass of 43.9 kDa. Its subcellular localization is in the lysosomes. Alternative splicing is reported to yield 2 different isoforms for this protein. A member of a the GLMP protein family, GLMP is known to be required to protect lysosomal transporter MFSD1 from lysosomal proteolysis and for MFSD1 lysosomal localization. Post-translational modifications have been described, including N-glycosylation. Synonyms for this target antigen include kidney predominant protein NCU-G1, lncRNA up-regulating CDK6 by interacting with DHX9, lysosomal protein NCU-G1, and kidney lysosomal membrane protein.
