Anti-SLM-2 antibodies enable researchers to detect and measure the SLM-2 antigen in biological samples. This target is a reported synonym of the KHDRBS3 gene, which encodes KH RNA binding domain containing, signal transduction associated 3. This protein is known to function in mRNA processing, among other biological roles. The human version of SLM-2 has a canonical amino acid length of 346 residues and a protein mass of 38.8 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the nucleus of cells and widely expressed in many tissue types. SLM-2 is a member of the KHDRBS protein family.
