What's a GeneRIF?

A regulatory phosphorylation site on Mec1 controls chromatin occupancy of RNA polymerases during replication stress.
Title: A regulatory phosphorylation site on Mec1 controls chromatin occupancy of RNA polymerases during replication stress.
identifed direct physical interaction between the Rpb3 Pol II subunit and the Mediator subunit, Med17; findings suggest a direct interaction between Mediator and Pol II is generally required for transcription of class II genes in eukaryotes
Title: Direct interaction of RNA polymerase II and mediator required for transcription in vivo.
