Kif26b, a new component of the evolutionarily conserved Wnt5a-Ror signaling pathway, is controlled by regulated proteolysis and plays crucial roles in mediating vertebrate embryonic tissue morphogenesis.
Accessible cholesterol levels in human red blood cells were found to be stable within individuals but vary >10-fold among individuals and this variability may contribute to differences in cholesterol trafficking among tissues.
Signals from primate rod photoreceptors do not exhibit the light-level-dependent routing through parallel retinal circuits observed in rodents and often invoked in interpreting psychophysical experiments.
The helical rod structure and dynamic spring-like properties of the type 1 pilus are evolutionarily fine-tuned for functioning in host-pathogen interactions during urinary tract infection and gut colonization.
A novel regulatory step in the endocytic pathway, which occurs post-internalization, takes place at the trans-Golgi network and involves the arrestin-related protein Rod1 and the ubiquitin ligase Rsp5.
