Anti-SYL antibodies enable researchers to detect and measure the SYL antigen in biological samples. This target is a reported synonym of the SYCN gene, which encodes syncollin. This protein is known to function in exocytosis, among other biological roles. The human version of SYL has a canonical amino acid length of 134 residues and a protein mass of 14.4 kilodaltons. It is reported to be localized in the membrane of cells and notably expressed in the pancreas.
