这个基因编码的蛋白质参与天冬酰胺的合成。这个基因补充了温度敏感型仓鼠突变体TS11的突变，该突变体在非耐受温度下阻止细胞周期G1期的进展。另外，还描述了该基因的剪接转录变体。
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.
