該基因編碼一個含有蛋白質的無菌α基序結構域。編碼蛋白定位于細胞質，可能在調節細胞增殖和凋亡中發揮作用。該基因突變是正常血壓家族性腫瘤鈣質沉著癥的原因交替剪接導致編碼相同蛋白質的多個轉錄變體。
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.
