Recently, neuroligins (NLs)3 and 4X have received much attention as autism-related genes. Here, we identified syntrophin-gamma2 (SNTG2) as a de novo binding partner of NL3. SNTG2 also bound to NL4X and NL4Y. Interestingly, the binding was influenced by autism-related mutations, implying that the impaired interaction between NLs and SNTG2 contributes to the etiology of autism.
