Organization of the synaptonemal complex during meiosis in Caenorhabditis elegans.
Four different SYP proteins (SYP-1, SYP-2, SYP-3, and SYP-4) have been proposed to form the central region of the synaptonemal complex (SC) thereby bridging the axes of paired meiotic chromosomes in Caenorhabditis elegans. Their interdependent localization suggests that they may interact within the SC. Our studies reveal for the first time how these SYP proteins are organized in the central reg...
متن کاملThe CSN/COP9 Signalosome Regulates Synaptonemal Complex Assembly during Meiotic Prophase I of Caenorhabditis elegans
The synaptonemal complex (SC) is a conserved protein structure that holds homologous chromosome pairs together throughout much of meiotic prophase I. It is essential for the formation of crossovers, which are required for the proper segregation of chromosomes into gametes. The assembly of the SC is likely to be regulated by post-translational modifications. The CSN/COP9 signalosome has been sho...
متن کاملMeiotic recombination modulates the structure and dynamics of the synaptonemal complex during C. elegans meiosis
During meiotic prophase, a structure called the synaptonemal complex (SC) assembles at the interface between aligned pairs of homologous chromosomes, and crossover recombination events occur between their DNA molecules. Here we investigate the inter-relationships between these two hallmark features of the meiotic program in the nematode C. elegans, revealing dynamic properties of the SC that ar...
متن کاملInduction of germline apoptosis in Caenorhabditis elegans.
RNA interference (RNAi) is an incredibly powerful tool for rapid and efficient knockdown of gene expression. This technology can be used to induce apoptosis in the germline of Caenorhabditis elegans. Genotoxic stressors such as ionizing radiation (IR), ultraviolet light, chemical mutagens (e.g., N-ethyl-N-nitrosourea [ENU]), and DNA cross-linking reagents can also be used to stimulate apoptosis...
متن کاملThe Caenorhabditis elegans Elongator Complex Regulates Neuronal α-tubulin Acetylation
Although acetylated alpha-tubulin is known to be a marker of stable microtubules in neurons, precise factors that regulate alpha-tubulin acetylation are, to date, largely unknown. Therefore, a genetic screen was employed in the nematode Caenorhabditis elegans that identified the Elongator complex as a possible regulator of alpha-tubulin acetylation. Detailed characterization of mutant animals r...
