Anti-IRIP antibodies enable researchers to detect and measure the IRIP antigen in biological samples. This target is a reported synonym of the YRDC gene, which encodes yrdC N6-threonylcarbamoyltransferase domain containing. The human version of IRIP has a canonical amino acid length of 279 residues and a protein mass of 29.3 kilodaltons. It is reported to be localized in the cell membrane, mitochondria, and cytoplasm of cells and notably expressed in many tissues, such as the pancreas and stomach. IRIP is a member of the SUA5 protein family.
