Anti-GLTPD1 antibodies enable researchers to detect and measure the GLTPD1 antigen in biological samples. This target is a reported synonym of the CPTP gene, which encodes ceramide-1-phosphate transfer protein. This protein is known to function in the metabolism of lipids and autophagy pathways, among other biological roles. The human version of GLTPD1 has a canonical amino acid length of 214 residues and a protein mass of 24.4 kilodaltons. It is reported to be localized in the cell membrane, nucleus, Golgi, and cytoplasm of cells and notably expressed in the duodenum and small intestine. GLTPD1 is a member of the GLTP protein family.
