Although puromycin staining is often used to examine subcellular translation, puromycin-labeled proteins are rapidly released from ribosomes even in the presence of elongation inhibitors, which may confound translation site localization.
Alms1a is a centrosomal protein that exhibits asymmetric localization between mother and daughter centrosomes in asymmetrically dividing stem cells in Drosophila testis, controlling centriole duplication.
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.
Structural and functional analysis of a new class of low-molecular-weight antibody fragments, derived from bovine immunoglobulins, reveals their therapeutic potential against C5, a target for refractory inflammatory diseases.
Synaptotagmin-7 acts synergistically with synaptotagmin-1 by placing vesicles close to the plasma membrane within reach of the SNARE/Munc13-complex, supporting their priming and setting the stage for fast and slow fusion.
