Anti-ribosome binding factor A (putative) antibodies enable researchers to detect and measure the ribosome binding factor A (putative) antigen in biological samples. This target is a reported synonym of the RBFA gene, which encodes ribosome binding factor A. This protein is known to function in rRNA processing, among other biological roles. The human version of ribosome binding factor A (putative) has a canonical amino acid length of 343 residues and a protein mass of 38.4 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the mitochondria of cells and widely expressed in many tissue types. Other names for this target antigen include putative ribosome-binding factor A, mitochondrial and ribosome binding factor A (putative).
