這個基因編碼的蛋白質參與天冬酰胺的合成。這個基因補充了溫度敏感型倉鼠突變體TS11的突變，該突變體在非耐受溫度下阻止細胞周期G1期的進展。另外，還描述了該基因的剪接轉錄變體。
The protein encoded by this gene is involved in the synthesis of asparagine. This gene complements a mutation in the temperature-sensitive hamster mutant ts11, which blocks progression through the G1 phase of the cell cycle at nonpermissive temperature. Alternatively spliced transcript variants have been described for this gene.
