這個基因編碼的蛋白質是突觸前細胞骨架基質的一部分，它參與建立活躍的突觸區和突觸小泡的運輸該基因的變異與雙相情感障礙和重度抑郁障礙有關已經發現了兩個編碼不同亞型的轉錄變體。
The protein encoded by this gene is part of the presynaptic cytoskeletal matrix, which is involved in establishing active synaptic zones and in synaptic vesicle trafficking. Variations in this gene have been associated with bipolar disorder and major depressive disorder. Two transcript variants encoding different isoforms have been found for this gene.
