Anti-TMEM257 antibodies enable researchers to detect and measure the TMEM257 antigen in biological samples. This target is a reported synonym of the SLITRK2 gene, which encodes SLIT and NTRK like family member 2. This protein is known to function in neuronal development, among other biological roles. The human version of TMEM257 has a canonical amino acid length of 845 residues and a protein mass of 95.4 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the cell membrane of cells. TMEM257 is a member of the SLITRK protein family.
