POF lovers which have transcripts from the fourth chromosome
We end you to definitely POF try graced to your nascent RNAs transcribed from family genes to your next chromosome and this creates expression output from the increasing the quantity of chromosome 4 transcripts. Also, conveyed genes in some HP1-rich regions, including the pericentromeric nations as well as the next chromosome, showcase improved change rates, we.e., the brand new RNA encrypted from genetics on these nations spends less time regarding nuclei than just really does that from family genes inside the regular euchromatic nations.

Into the Drosophila melanogaster, a few chromosome-greater compensatory solutions have been classified: the fresh MSL cutting-edge, which goals and you may builds the term of X-chromosome in males, and you will POF, which aim and you will builds the expression of your own next chromosome (34, 66). It has been hypothesized the MSL state-of-the-art builds phrase by the facilitating transcriptional elongation, and that hypothesis was has just affirmed experimentally (32). Here, we have made use of RNA immunoprecipitation and transcriptome profiling solutions to then explain the fresh new process by which POF creates gene expression.
I have in past times found you to POF binds to help you effective genetics to the the fresh new last chromosome (27).
