Objective To identify single nucleotide polymorphisms (SNPs) of human CatSper gene, the mouse homologous gene product, which plays a crucial role in mouse male sterility. Methods We demonstrated a systematic screening of SNPs in coding regions and flanking intronic regions of human CatSper gene in a sample subset from a total 210 male individuals by DNA sequencing. Then we used PCR single-stran...

Next-generation sequencing (NGS) is widely used to identify the causative mutations underlying diverse human diseases, including cancers, which can be useful for discovering the diagnostic and therapeutic targets. Currently, a number of single-nucleotide variant (SNV)-calling algorithms are available; however, there is no tool for visualizing the recurrent and phenotype-specific mutations for g...

a mixture oftrimethylchlorosilane (tms-cl), lithium and tetrahydrofuran (thf) reacts with imines to produce disilyl compound by addition of two trimethylsilyl (tms) groups to the double bond of the imine. on hydrolysis the tms on nitrogen is substituted by hydrogen and yields ? -silylamine. in the presence of acetyl chloride (ch coc1), benzene and pyridine, the ?-silyamine produces the correspo...

Discovery of potentially deleterious sequence variants is important and has wide implications for research and generation of new hypotheses in human and veterinary medicine, and drug discovery. The GenProBiS web server maps sequence variants to protein structures from the Protein Data Bank (PDB), and further to protein-protein, protein-nucleic acid, protein-compound, and protein-metal ion bindi...

The cAMP-binding protein Epac is a therapeutic target for the treatment of various diseases such as cardiac hypertrophy and tumor invasion. This points out the importance to develop Epac inhibitors to better understand the involvement of these cAMP sensors in physiology and pathophysiology. Here, we have developed a functional fluorescence-based high-throughput assay with a Z' value around 0.7 ...

The signaling pathways mediated by Rho family GTPases have been implicated in many aspects of cell biology. The specificity of the pathways is achieved in part by the selective interaction between Dbl family guanine nucleotide exchange factors (GEFs) and their Rho GTPase substrates. Here, we report a first-generation small-molecule inhibitor of Rac GTPase targeting Rac activation by GEF. The ch...
