The elongation rate of RNA Polymerase II varies greatly between and along genes, as this enzyme accelerates from stable pausing to rapid elongation within genes, and is influenced by CG-content, exons and chromatin.
Novel insights into LIS1-dependent regulation of cell membrane contractility and cleavage axis specification identify a key molecular network regulating mitoses of neural progenitors and somatic cells during development.
C. elegans equalizes the expression of X-chromosome genes between the sexes by reducing the recruitment of RNA polymerase II to promoters of X-linked genes in hermaphrodites, using a chromosome-restructuring complex called condensin.
To leverage the tools, resources and knowledge that exist for C. elegans so that we can study ecology, evolution and other aspects of biology, we need to understand the natural history of this important model organism.
NHE1-CaM complexes of multiple stoichiometries regulate cellular Ca2+-dependent NHE1 activity and can contribute to NHE1 dimerization, the latter shown by the NMR structure of CaM linking two NHE1 cytosolic tails.
