Project description:This submission contains datasets from several species used to demonstrate new features in compareMS2 2.0. Tandem mass spectrometry data from California sea lion, chimpanzee, dog, human, rock hyrax, and white-tailed deer sera were graciously provided with permission from an ongoing collaboration with Dr. Michael G. Janech (College of Charleston) as part of the CoMPARe Program (Comparative Mammalian Proteome Aggregator Resource). Specifically, the California sea lion sera were provided by The Marine Mammal Center (Sausalito, CA), the chimpanzee, rock hyrax, and white-tailed deer sera were provided by The Chattanooga Zoo, and the dog serum from Gus (Ohlandt Veterinary Clinic, Charleston, SC). In addition to institutional and NMFS permits and approval, data collection was performed under NIST ACUC MML-AR20-0001. The identification of certain commercial equipment, instruments, software, or materials does not imply recommendation or endorsement by the National Institute of Standards and Technology, nor does it imply that the products identified are necessarily the best available for the purpose.

Project description:Universal Minicircle Sequence binding proteins (UMSBPs) are CCHC-type zinc-finger proteins that bind the single-stranded G-rich UMS sequence, conserved at the replication origins of minicircles in the kinetoplast DNA, the mitochondrial genome of trypanosomatids. Trypanosoma brucei UMSBP2 has been recently shown to colocalize with telomeres and play an essential role in chromosome ends protection. Here we report that TbUMSBP2 decondenses in vitro DNA molecules, which were condensed by core histones H2B, H4 or linker histone H1. DNA decondensation is mediated via protein-protein interactions between TbUMSBP2 and these histones, independently of its, previously described, DNA binding activity. Silencing of the TbUMSBP2 gene resulted in a significant decrease in the disassembly of nucleosomes in T. brucei chromatin, a phenotype that could be reverted, by supplementing the knockdown cells with TbUMSBP2. Transcriptome analysis revealed that silencing of TbUMSBP2 affects the expression of multiple genes in T. brucei, with a most significant effect on the upregulation of the subtelomeric variant surface glycoproteins (VSG) genes, which mediate the antigenic variation in African trypanosomes. These observations suggest that UMSBP2 is a chromatin remodeling protein that functions in the regulation of gene expression that plays a role in the control of antigenic variation in T. brucei.
