Anti-UIP4 antibodies enable researchers to detect and measure the UIP4 antigen in biological samples. This target is a reported synonym of the RNF144A gene, which encodes ring finger protein 144A. This protein is known to function in protein ubiquitination, among other biological roles. The human version of UIP4 has a canonical amino acid length of 292 residues and a protein mass of 32.9 kilodaltons. It is reported to be localized in the cytoplasmic vesicles and cell membrane of cells and widely expressed in many tissue types. UIP4 is a member of the RBR protein family.
