Anti-Neurexin2 antibodies enable researchers to detect and measure the Neurexin2 antigen in biological samples. This target is a reported synonym of the NRXN2 gene, which encodes neurexin 2. This protein is known to function in signal transduction pathways, among other biological roles. The human version of Neurexin2 has a canonical amino acid length of 666 residues and a protein mass of 70.9 kilodaltons, although 3 isoforms have been identified. It is reported to be localized in the cell membrane of cells. Neurexin2 is a member of the Neurexin protein family.
