Anti-ES130 antibodies enable researchers to detect and measure the ES130 antigen in biological samples. This target is a reported synonym of the RRBP1 gene, which encodes ribosome binding protein 1. This protein is known to function in osteoblast differentiation and protein transport, among other biological roles. The human version of ES130 has a canonical amino acid length of 1410 residues and a protein mass of 152.5 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the ER of cells and widely expressed in many tissue types.
