Sin1, a regulatory subunit of TOR protein kinase, has an evolutionarily conserved domain that specifically binds and recruits substrate for phosphorylation, and may represent a potential target for anti-cancer drugs.
The pro-apoptotic BH3-protein Bim contains two distinct binding sites for anti-apoptotic proteins that together confer resistance of Bim/Bcl-2 and Bim/Bcl-XL complexes to BH3-mimetic drugs under development for use in humans.
A combination of detailed sampling and mathematical modeling suggests that the response of immune cells to reactivation of herpes simplex virus 2 is extremely rapid and effective within microscopic areas of genital skin.
In filamentous fungi the AP-2 complex, which in mammals is an adaptor of clathrin-mediated endocytosis, is recruited to specific clathrin-independent apical endocytosis necessary for proper lipid maintenance and polar growth.
The convergent evolution of yeast Mim1/2 and trypanosomal pATOM36 enable the first demonstration of reciprocal functional rescue of two evolutionary unrelated mitochondrial biogenesis complexes belonging to two different eukaryotic supergroups.
