Anti-VPS55 antibodies enable researchers to detect and measure the VPS55 antigen in biological samples. This target is a reported synonym of the LEPROTL1 gene, which encodes leptin receptor overlapping transcript like 1. The human version of VPS55 has a canonical amino acid length of 131 residues and a protein mass of 14.4 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the membrane of cells. VPS55 is a member of the OB-RGRP/VPS55 protein family.
