该基因编码叶酸聚谷氨酸合成酶这种酶在建立和维持细胞液和线粒体的叶酸多聚谷氨酸浓度方面起着中心作用，因此，对于叶酸的稳态和增殖细胞的生存至关重要这种酶催化谷氨酸部分对叶酸和叶酸衍生物的ATP依赖性加成选择性剪接导致编码不同亚型的转录变体。[由RefSeq提供，2014年1月]
This gene encodes the folylpolyglutamate synthetase enzyme. This enzyme has a central role in establishing and maintaining both cytosolic and mitochondrial folylpolyglutamate concentrations and, therefore, is essential for folate homeostasis and the survival of proliferating cells. This enzyme catalyzes the ATP-dependent addition of glutamate moieties to folate and folate derivatives. Alternative splicing results in transcript variants encoding different isoforms.
