Anti-MTMR13 antibodies enable researchers to detect and measure the MTMR13 antigen in biological samples. This target is a reported synonym of the SBF2 gene, which encodes SET binding factor 2. This protein is known to function in autophagy pathways, among other biological roles. The human version of MTMR13 has a canonical amino acid length of 1849 residues and a protein mass of 208.5 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the membrane and cytoplasm of cells. MTMR13 is a member of the Protein-tyrosine phosphatase protein family.
