What's a GeneRIF?

The Eaf3 chromodomain acts as a pH sensor for gene expression by altering its binding affinity for histone methylated-lysine residues.
Title: The Eaf3 chromodomain acts as a pH sensor for gene expression by altering its binding affinity for histone methylated-lysine residues.
Eaf3 is recruited to intron-containing genes and that Eaf3 interacts with the splicing factor Prp45. Eaf3 acts with Prp45 and Prp19 after formation of the precatalytic B complex around the time of splicing activation, thus revealing the step in splicing that is regulated by H3K36 methylation.
Title: H3K36 Methylation and the Chromodomain Protein Eaf3 Are Required for Proper Cotranscriptional Spliceosome Assembly.
Results demonstrate that the combination of Eaf3 and Yng2 interactions with their respective methyl marks on histone H3 is not important for NuA4 localization on the genome but is required for proper H4 acetylation throughout the transcription unit.
Title: Combined Action of Histone Reader Modules Regulates NuA4 Local Acetyltransferase Function but Not Its Recruitment on the Genome.
In vitro binding assays showed that Eaf3/5/7 specifically stimulates NuA4 binding to di- and trimethylated histone H3 Lys-36 and that this binding is important for NuA4 occupancy in transcribed ORFs.
Title: The Eaf3/5/7 Subcomplex Stimulates NuA4 Interaction with Methylated Histone H3 Lys-36 and RNA Polymerase II.
analysis of the molecular mechanism of the recognition and binding of the methylated H3K36 by Eaf3 provides new insights into the functional roles of the Eaf3 chromo domain
Title: Molecular basis of the interaction of Saccharomyces cerevisiae Eaf3 chromo domain with methylated H3K36.
The association of Rpd3S with chromatin requires its Eaf3 subunit, which binds histone H3 methylated at lysine 36.
Title: Structural basis for the recognition of methylated histone H3K36 by the Eaf3 subunit of histone deacetylase complex Rpd3S.
Data show that Eaf3 interaction with methylated histone H3 links histone deacetylation to RNA polymerase II elongation.
Title: Eaf3 chromodomain interaction with methylated H3-K36 links histone deacetylation to Pol II elongation.
