Anti-SNX1 antibodies are used in the immunodetection of the protein sorting nexin 1. In humans, the canonical protein has a reported length of 522 amino acid residues and a mass of 59.1 kDa. Its subcellular localization is in the endosome, golgi, and membrane. Alternative splicing is reported to yield 3 different isoforms for this protein. A member of a the Sorting nexin protein family, SNX1 is known to be involved in several stages of intracellular trafficking. Synonyms for this target antigen include VPS5, sorting nexin 1A, and HsT17379.
