The autoantigen La protein is a conserved component of eukaryotic ribonucleoprotein complexes that binds the 3' poly(U) sequences of nascent RNA polymerase III transcripts to assist folding and maturation. This specific recognition is mediated by the N-terminal domain (NTD) of La, which comprises a La motif and an RNA recognition motif (RRM). Here, we report near complete H, C and N backbone and sidechain assignments for the RRM domain of La protein from Trypanosoma brucei.
自身抗原 La 蛋白是真核核糖核蛋白复合物的保守成分,它与新生 RNA 聚合酶 III 转录本的 3' 聚(U)序列结合,以协助折叠和成熟。这种特异性识别由 La 的 N 端结构域(NTD)介导,它包含一个 La 基序和一个 RNA 识别基序(RRM)。在这里,我们报道了来自布氏锥虫的 La 蛋白的 RRM 结构域的 H、C 和 N 骨架及侧链的几乎完整的归属。
