Anti-Clavesin 1 antibodies are used in the immunodetection of the protein encoded by the CLVS1 gene. In humans, the canonical protein has a reported length of 354 amino acid residues and a mass of 40.8 kDa. Its subcellular localization is in the cytoplasmic vesicles, golgi, and membrane. Alternative splicing is reported to yield 2 different isoforms for this protein. It is notably expressed in the brain. It is reported to be required for normal morphology of late endosomes and/or lysosomes in neurons (By similarity). Other names for this target antigen include clathrin vesicle-associated Sec14 protein 1 and retinaldehyde-binding protein 1-like 1.
