Nanos是涉及生殖细胞发育的进化保守蛋白之一,我们以前已经证明它与CCR4-NOT去腺苷复合物相互作用,导致特异性RNA的抑制。然而,这种相互作用的分子机制和生理意义仍然是难以捉摸的。在我们目前的研究中,我们确定了hocT1,CCR4-NOT deadenylation复合物的一个组成部分,作为介导与NANOS2相互作用的直接因子。我们发现NANOS2的前10个氨基酸(AAs)是这种结合所必需的。我们进一步观察到,缺乏这前10个AA的NANOS2突变体(NANOS2-Δ N10)未能挽救Nanos2缺失小鼠中的缺陷。因此,我们目前的数据表明,与CCR 4-NOT去腺苷化复合物的相互作用对NANOS 2功能至关重要。此外,我们进一步证明了NANOS2-Δ N10可以与特定的mRNA以及野生型NANOS2结合,这表明存在其他NANOS2相关因子,这些因子独立于CCR 4-NOT去腺苷化复合物决定RNA结合的特异性。
Nanos is one of the evolutionarily conserved proteins implicated in germ cell development and we have previously shown that it interacts with the CCR4-NOT deadenylation complex leading to the suppression of specific RNAs. However, the molecular mechanism and physiological significance of this interaction have remained elusive. In our present study, we identify CNOT1, a component of the CCR4-NOT deadenylation complex, as a direct factor mediating the interaction with NANOS2. We find that the first 10 amino acids (AAs) of NANOS2 are required for this binding. We further observe that a NANOS2 mutant lacking these first 10 AAs (NANOS2-ΔN10) fails to rescue defects in the Nanos2-null mouse. Our current data thus indicate that the interaction with the CCR4-NOT deadenylation complex is essential for NANOS2 function. In addition, we further demonstrate that NANOS2-ΔN10 can associate with specific mRNAs as well as wild-type NANOS2, suggesting the existence of other NANOS2-associated factor(s) that determine the specificity of RNA-binding independently of the CCR4-NOT deadenylation complex.
