SAMD9（sterile alpha motif domain containing 9），癌症关联基因，基因ID：54809，该基因编码一个含有蛋白质的无菌α基序结构域。编码蛋白定位于细胞质，可能在调节细胞增殖和凋亡中发挥作用。该基因突变是正常血压家族性肿瘤钙质沉着症的原因交替剪接导致编码相同蛋白质的多个转录变体。[由RefSeq提供，2010年7月]This gene encodes a sterile alpha motif domain-containing protein. The encoded protein localizes to the cytoplasm and may play a role in regulating cell proliferation and apoptosis. Mutations in this gene are the cause of normophosphatemic familial tumoral calcinosis. Alternate splicing results in multiple transcript variants that encode the same protein.[provided by RefSeq， Jul 2010]。
