Transcription at the proximity of the nuclear pore: A role for the THP1-SAC3-SUS1-CDC31 (THSC) complex

A key aspect of eukaryotic gene expression is the coupling of transcription with RNA processing, polyadenylation and export. The use of new techniques based on tandem affinity purification (TAP) and chromatin immunoprecipitation (ChIP), and of genetic and cell biology approaches has contributed to t...

Sumario:A key aspect of eukaryotic gene expression is the coupling of transcription with RNA processing, polyadenylation and export. The use of new techniques based on tandem affinity purification (TAP) and chromatin immunoprecipitation (ChIP), and of genetic and cell biology approaches has contributed to the beginning of deciphering the network of protein-mRNA interactions accompanying this coupling. Although an extensive amount of work has shed light on this matter, the order of participation and precise role of the different proteins remain to be deciphered. It seems that different and sequential protein interactions must converge to finally promote the anchoring of genes to the nuclear periphery. Here we discuss the new data on the coupling of gene expression and RNA export, with emphasis on the THP1-SAC3-SUS1-CDC31 complex and the possible implications of these results on transcription at the nuclear pore.
