(2018-04-19)Previous research indicates that Set1 is the catalytically active protein in COMPASS, a protein methyltransferase complex associated with transcription in budding yeast cells. However, the mechanistic role that Set1 and ...

(Texas A&M University, 2005-08-29)The reversible process of histone acetylation and deacetylation is an important mechanism of epigenetic regulation in the control of gene expression and chromatin structure. In general, histone acetylation is related to ...
-
(2010-10-12)Gene expression is a process that involves changes in chromatin organization and structure. Chromatin is thought to be organized in a structure consisting of looped domains, which are fixed at their bases to the nuclear matrix ...
-
(Texas A&M University, 2006-04-12)In eukaryotes, the organization of DNA into chromatin is a primary determinant of gene expression. Positioned nucleosomes in promoter regions are frequently found to regulate gene expression by obstructing the accessibility ...
-
(2008-08-24)Chromosomal DNA in our cells is wrapped around a histone protein octomer like thread on a spool, forming a structure called a nucleosome. Series of nucleosomes form the nuclear chromosomes found in all eukaryotic organisms. ...

(Texas A&M University, 2006-04-12)In higher eukaryotes, DNA is packaged with histones and other proteins into chromatin. While this is important in the control of unwanted gene expression, chromatin also serves as a barrier to many vital functions in the ...
-
(Texas A&M University, 2005-08-29)Regulation of gene expression is vital for proper growth and prevention of disease states. In eukaryotes this regulation occurs in the context of chromatin which creates an inherent barrier for the binding of trans-acting ...

(Texas A&M University, 2006-10-30)The phaseolin (phas) promoter drives the copious production of transcripts encoding the protein phaseolin during seed embryogenesis but is silent in vegetative tissues when a nucleosome is positioned over its three phased ...
