Project description:We investigated seminal fluid (SF) diversification in a recently diverged passerine species pair (Passer domesticus and P. hispaniolensis) using a combination of proteomic and comparative evolutionary genomic approaches. Specifically, using tandem MS/MS semi-quantitative proteomic methods we identified and compared the SF proteome of two species of Passer sparrows - the house and Spanish sparrow. This analysis revealed consistencies with known aspects of SF protein biology and function in other taxa, including the presence of a diversity of immune and antimicrobial proteins
Project description:Using wild type and Ash1l ?SET mutant embryonic stem cells, against a prevalent notion, here we report di-,tri-methylation of histone H3 Lys36 occur independently of ongoing transcription. Ash1l ?SET mutant shows the impaired methylation levels in broad range of genome. Intriguingly, data implicate that a binding of retinoic acid receptor to a certain genomic region promotes installation of the tri-methylation in the retinoic acid receptor-associated gene independent of its ongoing transcription. Examination of 2 different histone modifications in 2 cell types in 2 different conditions. Examination of Ash1l occupancy in 2 different conditions.
