The 68 kDa subunit of mammalian cleavage factor I interacts with the U7 small nuclear ribonucleoprotein and participates in 3′-end processing of animal histone mRNAs [PDF]
Metazoan replication-dependent histone pre-mRNAs undergo a unique 3′-cleavage reaction which does not result in mRNA polyadenylation. Although the cleavage site is defined by histone-specific factors (hairpin binding protein, a 100-kDa zinc-finger ...

Function of AFF1 in P-TEFb network [PDF]
在真核细胞中,编码蛋白的基因转录是由RNA聚合酶II(RNAPolII)通过一系列复杂有序的调控机制完成的。不断深入的研究表明过去不受重视的转录延伸步骤也存在高度有序,极为精细的调控机制,这主要得益于正性转录延伸因子b(positive-transcriptionelongationfactorb,P-TEFb)的发现及对其功能的研究。P-TEFb复合体是由激酶CDK9(Cyclindependentkinase)及其调节亚基CycT1(CyclinT1)组成的异二聚体 ...

A unique mechanism of snRNP core assembly
The assembly of most spliceosomal snRNP cores involves seven Sm proteins (D1/D2/F/E/G/D3/B) forming a ring around snRNA, typically requiring essential assembly chaperones like the SMN complex, associated with spinal muscular atrophy (SMA). Strikingly, in

Addressing the tissue specificity of U5 snRNP spliceosomopathies
Precursor mRNA (pre-mRNA) must undergo splicing to remove intron sequences and join exons. This splicing process is catalysed by an RNA/protein complex called the spliceosome.
