关于 DDX54

功能概要

该基因编码 DEAD box 蛋白家族的一个成员。以保守基序 Asp-Glu-Ala-Asp (DEAD) 为特征的 DEAD 盒蛋白是推定的 RNA 解旋酶。它们涉及许多涉及 RNA 二级结构改变的细胞过程，例如翻译起始、核和线粒体剪接以及核糖体和剪接体组装。根据它们的分布模式，该家族的一些成员被认为参与了胚胎发生、精子发生以及细胞生长和分裂。由该基因编码的核仁蛋白以激素依赖性方式与核受体相互作用，并抑制其转录活性。已发现该基因编码不同亚型的可变剪接变体。[RefSeq 提供，2008 年 7 月]

This gene encodes a member of the DEAD box protein family. DEAD box proteins, characterized by the conserved motif Asp-Glu-Ala-Asp (DEAD), are putative RNA helicases. They are implicated in a number of cellular processes involving alteration of RNA secondary structure such as translation initiation, nuclear and mitochondrial splicing, and ribosome and spliceosome assembly. Based on their distribution patterns, some members of this family are believed to be involved in embryogenesis, spermatogenesis, and cellular growth and division. The nucleolar protein encoded by this gene interacts in a hormone-dependent manner with nuclear receptors, and represses their transcriptional activity. Alternative splice variants that encode different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]
