Now the functions of Alu elements are still unclear . It is speculated that Alu elements are involved in aspects of gene regulation , e.g. gene rearrangement , CpG methylation , alternative splicing of hnRNA , binding sites of transcription factors and hormone receptors , etc.
目前,对于Alu序列的功能了解得还不透彻,据推测主要与基因调控有关,如基因重排、CpG甲基化、hnRNA选择性剪切、结合转录因子和激素等。

When gene was transcripted from cell nucleus , the new-synthesized pre-mRNA or hnRNA become mature RNA through a series of responses such as add-cap , splice of pre-mRNA , compose poly-A et al . Then the mature mRNA was transport to cytoplasm .
基因从核内转录后,新合成的pre-mRNA或核异质RNA(hnRNA)通过加帽、pre-mRNA的剪接、合成多聚腺苷酸(PolyA)尾等一系列的反应而成为成熟的mRNA。
