Sorbin and SH3 domain containing 3 (SORBS3) consists of two transcript variants that code for two protein isoforms, vinexin alpha and beta, respectively. Variant 2 (vinexin beta) exons 3–10 are consistent with variant 1 exons 14–21, containing all three SH3 domains. Variant 2 differs by lacking the coding regions for the N-terminal end SoHo domain
