Biological pathways have the ability to tolerate mutations and evolve to control novel traits. Selection pressures act on these pathways playing a key role in the evolution and divergence of species. Sex determination in Caenorhabditis nematodes is a rapidly evolving trait which can provide...

Drosophila ATM and ATR have distinct activities in the regulation of meiotic DNA damage and repair

Ataxia telangiectasia–mutated (ATM) and ataxia telangiectasia–related (ATR) kinases are conserved regulators of cellular responses to double strand breaks (DSBs). During meiosis, however, the functions of these kinases in DSB repair and the deoxyribonucleic acid (DNA) damage checkpoint are...

In the newly fertilized embryo, meiotic and mitotic spindles form consecutively within the same egg cytoplasm. The order of events during this transition is controlled, in part, via the regulation of the microtubule cytoskeleton. Herein, I show that mel-43 is part of a small paralogous gene...

Meiosis in eukaryotes includes a developmentally programmed pre-meiotic G2 phase arrest before the onset of MI division mediated by inhibitory phosphorylation of Cdk1. There are two inhibitory kinases, Wee1 and Myt1. Myt1 mediated Cyclin B-Cdk1 regulation serves as a conserved mechanism for...

Mapping and characterization of mel-43(sb41), a gene required for early embryonic viability in C. elegans
DownloadSpring 2010
A genetic screen for dominant, temperature-sensitive, maternal-effect embryonic lethal mutations identified mel-43(sb41), a gene required for early embryonic viability (Mitenko et al., 1997). Linkage mapping placed mel-43 within a small region on chromosome IV. Genetic analyses suggested that...
