該基因編碼二酰甘油激酶（DGK）酶家族的一個成員。這個家族的成員參與調節二酰甘油和磷脂酸的細胞內濃度。這種基因的變異與雙相情感障礙有關。另外，還發現了剪接轉錄變體。
This gene encodes a member of the diacylglycerol kinase (DGK) enzyme family. Members of this family are involved in regulating intracellular concentrations of diacylglycerol and phosphatidic acid. Variation in this gene has been associated with bipolar disorder. Alternatively spliced transcript variants have been identified.
