实体肿瘤检测CDA基因介绍
这个基因编码一种参与嘧啶抢救的酶。编码蛋白形成一个四聚体，分别催化胞苷和脱氧胞苷不可逆水解脱氨为尿苷和脱氧尿苷。它是维持细胞嘧啶池的几种脱氨酶之一。该基因突变与用于治疗某些儿童白血病的胞嘧啶核苷类似物阿糖胞苷敏感性降低有关。
This gene encodes an enzyme involved in pyrimidine salvaging. The encoded protein forms a homotetramer that catalyzes the irreversible hydrolytic deamination of cytidine and deoxycytidine to uridine and deoxyuridine, respectively. It is one of several deaminases responsible for maintaining the cellular pyrimidine pool. Mutations in this gene are associated with decreased sensitivity to the cytosine nucleoside analogue cytosine arabinoside used in the treatment of certain childhood leukemias.
