该基因编码短链脱氢酶/还原酶（SDR）蛋白家族的一个成员该基因跨越FRA16D染色体上常见的脆性位点，具有抑癌基因的功能编码蛋白的表达能够诱导细胞凋亡，而该基因的缺陷与多种类型的癌症有关。这种基因的破坏也与常染色体隐性遗传脊髓小脑共济失调12有关。在小鼠中，类似基因的破坏导致类固醇生成受损，此外还表明该蛋白具有代谢功能。选择性剪接导致多个转录变体[由RefSeq提供，2014年5月]
This gene encodes a member of the short-chain dehydrogenases/reductases (SDR) protein family. This gene spans the FRA16D common chromosomal fragile site and appears to function as a tumor suppressor gene. Expression of the encoded protein is able to induce apoptosis, while defects in this gene are associated with multiple types of cancer. Disruption of this gene is also associated with autosomal recessive spinocerebellar ataxia 12. Disruption of a similar gene in mouse results in impaired steroidogenesis, additionally suggesting a metabolic function for the protein. Alternative splicing results in multiple transcript variants.
