Anti-ARRS1 antibodies enable researchers to detect and measure the ARRS1 antigen in biological samples. This target is a reported synonym of the RBM27 gene, which encodes RNA binding motif protein 27. This protein is known to function in mRNA processing, among other biological roles. The human version of ARRS1 has a canonical amino acid length of 1060 residues and a protein mass of 118.7 kilodaltons. It is reported to be localized in the nucleus and cytoplasm of cells and widely expressed in many tissue types.
