'Males heterozygous for the t-haplotype form of mouse chromosome 17 preferentially transmit the t-chromosome to their progeny. Several distorter/sterility loci carried on the t-haplotype together impair flagellar function in all spermatozoa whereas the responder, Tcr, rescues t-sperm but not wild-type sperm. Thus, t-sperm have anadvantage over wild-type sperm in fertilizing ... More
DNA Polymerase lambda, a Novel DNA Repair Enzyme in Human Cells.
'DNA polymerase lambda (pol lambda) is a novel family X DNA polymerase that has been suggested to play a role in meiotic recombination and DNA repair. The recent demonstration of an intrinsic 5''-deoxyribose-5-phosphate lyase activity in pol lambda supports a function of this enzyme in base excision repair. However, the ... More

'We have used a combination of in vitro selection and rational design to generate ribozymes that form a stable phosphoamide bond between the 5'' terminus of an RNA and a specific polypeptide. This reaction differs from that of previously identified ribozymes, although the product is analogous to the enzyme-nucleotidyl intermediates ... More
Transduction of MIN6 beta Cells with TAT-Syntaxin SNARE Motif Inhibits Insulin Exocytosis in Biphasic Insulin Release in a Distinct Mechanism Analyzed by Evanescent Wave Microscopy.
To investigate the in vivo interaction of syntaxin-mediated soluble N-ethylmaleimide-sensitive fusion protein attachment protein receptor (SNARE) assembly and insulin exocytosis in biphasic release, we examined the dynamics of insulin granule motion such as docking and fusion with the plasma membrane when the syntaxin SNARE motif (H3 domain) was transduced into ...
