Other Notes

Also recognizes 7-methylguanosine-capped mRNA. 2,2,7-trimethylguanosine (Ab-1) is human, mouse, and rat reactive. This antibody reacts with the exposed 5′ cap structure of the snRNAs and the antibody can be used for the purification of snRNPs by immunoaffinity chromatography. All of the major snRNPs bind to the monoclonal antibody column and can be gently eluted by washing with 7-methyl guanosine. Antibody should be titrated for optimal results in individual sample types.

The Cdk7 subunit of TFIIH phosphorylates RNA polymerase II (Pol II) during initiation, and, while recent studies show that inhibition of human Cdk7 negatively influences transcription, the mechanisms involved are unclear. Using in vitro transcription with nuclear extract, we demonstrate that

Recent studies showed that Rai1 is a crucial component of the mRNA 5'-end-capping quality-control mechanism in yeast. The yeast genome encodes a weak homolog of Rai1, Ydr370C, but little is known about this protein. Here we report the crystal structures

trans splicing of a spliced-leader RNA (SL RNA) to the 5' ends of mRNAs has been shown to have a limited and sporadic distribution among eukaryotes. Within metazoans, only nematodes are known to process polycistronic pre-mRNAs, produced from operon units

A unique feature of RNA polymerase II (RNA pol II) is its long C-terminal extension, called the carboxy-terminal domain (CTD). The well-studied eukaryotes possess a tandemly repeated 7-amino-acid sequence, called the canonical CTD, which orchestrates various steps in mRNA synthesis.

The biogenesis of splicing snRNPs (small nuclear ribonucleoproteins) is a complex process, beginning and ending in the nucleus of the cell but including key stages that take place in the cytoplasm. In particular, the SMN (survival motor neuron) protein complex
