Anti-C19orf77 antibodies enable researchers to detect and measure the C19orf77 antigen in biological samples. This target is a reported synonym of the SMIM24 gene, which encodes small integral membrane protein 24. The human version of C19orf77 has a canonical amino acid length of 130 residues and a protein mass of 15 kilodaltons. It is reported to be localized in the membrane of cells and notably expressed in the small intestine, ovary, kidney, epididymis, and duodenum.
