Histone-lysine N-methyltransferase SETD3 (NP_115609.2) was identified as the actin-specific histidine N-methyltransferase, an enzyme catalyzing the extremely well-conserved methylation of H73 in β-actin.
HIPPO signaling antagonizes the apical domain of polarized cells, driving cell internalization, regulated gene expression, and cell fate change during formation of pluripotent stem cell progenitors in the mouse embryo.
Extensive cytological and biochemical analyses show that the conserved Sf3A2 and Prp31 splicing factors bind microtubules and the Ndc80 complex, playing direct mitotic functions in both Drosophila and human mitosis.
Quantifiable bioenergetic parameters, determined from extracellular flux analyses, are distinct between macrophages infected with Mycobacteriumtuberculosis or vaccine strain M. bovis BCG, enabling assessment of future vaccine and drug efficacy.
The high-resolution structure of Rea1, an essential ribosome maturation factor in Saccharomyces cerevisiae, explains how the ATPase domain is regulated and reveals the linker domain, the mechanical element carrying out ribosome remodeling.
