Anti-CERS5 antibodies are used in the immunodetection of the protein ceramide synthase 5. In humans, the canonical protein has a reported length of 392 amino acid residues and a mass of 45.8 kDa. Its subcellular localization is in the ER. Up to 2 different isoforms have been reported for this protein. It is notably widely expressed in many tissue types. CERS5 is reported to be a ceramide synthase that catalyzes the transfer of the acyl chain from acyl-CoA to a sphingoid base, with high selectivity toward palmitoyl-CoA (hexadecanoyl-CoA; C16:0-CoA). Post-translational modifications have been described, including phosphorylation and glycosylation. Synonyms for this target antigen include LAG1 longevity assurance homolog 5, TRAM homolog 4, sphingoid base N-palmitoyltransferase CERS5, sphingosine N-acyltransferase CERS5, and LAG1 homolog, ceramide synthase 5. CERS5 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some CERS5 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. ELISA, Immunofluorescence, and Immunohistochemistry are also common applications.
