Nuclear pre-mRNA splicing proceeds via two mechanistically conserved consecutive trans-esterification reactions catalyzed by the spliceosome. The ordered coalescence of spliceosomal snRNPs and splicing factors on the ...

Tumor suppressor p53, the guardian of the genome, has been intensely studied molecule owing to its central role in maintaining cellular integrity. While the level of p53 protein is maintained low in unstressed conditions, ...

The process of eukaryotic transcription and its regulation has been an interesting area of research for decades. With more insights into the process of transcriptional regulation of genes, studies have revealed a ...

RNA polymerase II (Pol II) is the enzyme responsible for the synthesis of all mRNAs in eukaryotic cells. As the central component of the eukaryotic transcription machinery, Pol II is the final target of regulatory pathways. ...

DNA repair processes are crucial for mutation avoidance and the maintenance of genetic integrity in all organisms. Organisms rely on repair processes to combat genotoxic stress imposed by hostile host environment, and ...

A signal transduction process refers to chain of highly regulated biochemical steps which results in the transfer of signal in response to a stimulus in the extracellular environment to the intracellular compartments such ...
