Abstract

The 2'-5' oligoadenylate synthetases form a well conserved family of interferon induced proteins, presumably present throughout the mammalian class. Using the Expressed Sequence Tag databases, we have identified a novel member of this family. This protein, which we named p59 2'-5' oligoadenylate synthetase-like protein (p59OASL), shares a highly conserved N-terminal domain with the known forms of 2'-5' oligoadenylate synthetases, but differs completely in its C-terminal part. The C-terminus of p59OASL is formed of two domains of ubiquitin-like sequences. Here we present the characterisation of a full-length cDNA clone, the genomic sequence and the expression pattern of this gene. We have addressed the evolution of the 2'-5' oligoadenylate synthetase gene family, in the light of both this new member and new 2'-5' oligoadenylate synthetase sequence data from other species, which have recently appeared in the databases.

摘要

2'-5'寡腺苷酸合成酶构成了一个干扰素诱导蛋白的保守家族,可能存在于整个哺乳纲动物中。利用表达序列标签数据库,我们鉴定出了该家族的一个新成员。这种蛋白,我们将其命名为p59 2'-5'寡腺苷酸合成酶样蛋白(p59OASL),与已知形式的2'-5'寡腺苷酸合成酶共享一个高度保守的N端结构域,但其C端部分则完全不同。p59OASL的C端由两个泛素样序列结构域组成。在此,我们展示了该基因全长cDNA克隆的特征、基因组序列及其表达模式。鉴于这个新成员以及数据库中最近出现的来自其他物种的新2'-5'寡腺苷酸合成酶序列数据,我们探讨了2'-5'寡腺苷酸合成酶基因家族的进化。
