The reversible methylation of specific lysine residues in histone tails is crucial in epigenetic gene regulation. LSD1, the first known lysine-specific demethylase, selectively removes monomethyl and… (More)
The symmetric core of the nuclear pore complex can be considered schematically as a series of concentric cylinders. A peripheral cylinder coating the pore membrane contains the previously… (More)
Somatic hypermutation and class switch recombination are DNA modification reactions that alter the genes encoding antibodies in B lymphocytes. Both of these distinct reactions require… (More)
Somatic hypermutation (SHM) and class switch recombination (CSR) are initiated in activated B lymphocytes by activation-induced deaminase (AID). AID is thought to make lesions in DNA by deaminating… (More)

Rtt109 is a protein acetyltransferase (PAT) that is responsible for the acetylation of lysine-56 of histone 3 (H3K56) in yeast. H3K56 acetylation has been implicated in the weakening of the… (More)
The African trypanosome (Trypanosoma brucei) is transmitted by the bite of the tsetse vector to the mammalian bloodstream where it exists as a completely extracellular parasite. As a result of this… (More)
Chromatin is a highly dynamic structure that undergoes a variety of chemical modifications. These modifications mediate alterations of the chromatin architecture, generate binding platforms that are… (More)

Trypanosoma brucei PRMT7 (TbPRMT7) is a protein arginine methyltransferase (PRMT) that strictly monomethylates various substrates, thus classifying it as a type III PRMT. However, the molecular basis… (More)
