In this episode we hear about using electrons for protein crystallography, a receptor for carbon dioxide, arthritis, how the brain responds to a missing hand, and the best shape for whiskers.
Kinesin-4 KIF21B promotes rapid reorientation of the microtubule network during formation of immunological synapse in T cells by acting as a pausing and catastrophe-inducing factor that keeps microtubules short.
Heme accumulation is toxic, but deficiency of the heme transporter HRG1/SLC48A1 causes heme sequestration and crystallization into hemozoin within enlarged lysosomes of macrophages, thereby conferring heme tolerance to mammals.
The RNA-binding protein, Zfp36, which is critical for resolving inflammation, inhibits the production of proinflammatory cytokines via modulation of the cytoplasmic poly(A)-binding protein.
Blood flow-driven shear forces guide the sequential signaling of two antagonistic paired receptors, a critical bi-facet step that first supports leukocyte docking, then initiates transmigration through endothelium.
Combinatorial transcription factor binding shared by multiple species enriches for essential biological pathways and coincides with disease-causing regulatory DNA mutations.
Context-dependent optimization of Gli-binding site occupancy, in the presence of Hand2, is critical for modulating tissue-specific transcriptional output within tissues that lack an obvious Hedgehog morphogen gradient.
