总结:我们报告了一个先前未表征的CHHC锌指结构域,在剪接体U11- 48 K蛋白,tRNA甲基转移酶TRM 13和配子体特异性因子中鉴定。我们发现,这个域的行为作为一个独立的折叠单元,它的化学计量结合锌在一个一比一的比例。基于保守的序列特征,我们预测该结构域可能作为RNA识别和结合模块。联系方式:tony@mrc-lmb.cam.ac.uk补充信息:补充数据可在生物信息学在线上获得。
Summary: We report a previously uncharacterized CHHC Zn-finger domain identified in spliceosomal U11-48K proteins, tRNA methyl-transferases TRM13 and gametocyte specific factors. We show that this domain behaves as an independent folding unit and that it stoichiometrically binds zinc in a one-to-one ratio. Based on the conserved sequence features we predict that this domain may function as a RNA recognition and binding module.
