Trithoraxgroupproteins are chromatin regulatory proteins which generally act to maintain gene expression. This group of proteins is rather heterogeneous and contains members that form several multiprotein chromatin complexes. One main activity of the Trithorax complex is to activate transcription by inducing trimethylation of lysine 4 of histone H3 H3K4me3 at specific regulatory site s in their target chromatin. This active state is reinforced by acetylation of histone H4. In addition, some Trithoraxgroupproteins have chromatin remodeling activity, using the energy of ATP to mobilize nucleosomes. Polycomb groupproteins are the repressive counterpart to the Trithoraxgroupproteins in that they also bind to the chromatin at the Hox genes and act to induce trimethylation of lysine 27 of histone H3 H3K27me3 , to prevent acetylation at histone H4, and to counteract nuclesome remodeling, thus maintaining silent states of gene expression. br further2 MLL gene MLL ASH1L ASH2L References reflist http www.sdbonline.org fly aignfam polycomb.htm Chromatin organization and the Polycomb and Trithorax groups in The Interactive Fly Polycomb silencing mechanisms and the management of genomic programmes Y.

The proteins are post translationally modified via addition of a uridylyl group by the enzyme Uridylyltransferase . The presence or absence of this group modulates the behaviour of the protein. In turn, uridylation is controlled by cellular levels of alpha Ketoglutaric acid alpha ketoglutarate and Adenosine triphosphate ATP . PII proteins exist in trimers in vivo and bind ATP in a cleft between the subunits. There are two flexible loops call the B loop and T loop which are involved in regulation of the protein. The T loop contains a conserved tyrosine which is the site of uridyl attachment. Following nitrogen starvation, increased intra cellular concentrations of ammonia cause the de uridylylation of GlnK. This then binds directly to the ammonia transporter ammonia channel AmtB to block ammonia conduction. ref cite pmid 16864585 ref ref cite pmid 17220269 ref References reflist Category Proteins ... more details
