A ubiquitin E3 ligase localizes to focal adhesions at the front of migrating human cells where it regulates cytoskeletal dynamics by targeting a focal adhesion protein.
Ankyrin-B – through interactions with PI3P lipids, dynactin and RabGAP1L – functions as a critical node in the protein circuitry underlying polarized recycling of α5β1-integrin to enable haptotaxis along fibronectin gradients.
CPEB4's switch from translational repressor to activator is regulated during cell cycle by hyperphosphorylation of its intrinsically disordered domain, which controls its phase-separation into RNA-containing liquid-like droplets.
Carbonyl stress mediated by Methylglyoxal affects Hsp90 activity, inhibits the Hippo pathway and promotes tumor growth and metastasis in breast cancer.

Cytokinetic actomyosin ring disassembly occurs through a novel mechanism in which the increased ring curvature, generated through contraction, itself promotes the disassembly process.
Imaging, quantitative immunoblotting and mass spectrometry reveal that hundreds of surface-expressed neuronal membrane proteins exhibit atypical glycosylation profiles, resulting in changes in protein half-life and synaptic responses.
LAMP proteins, the major glycoproteins of the lysosome membrane, bind cholesterol directly and specifically, and interact with NPC1 and NPC2 proteins as part of the lysosomal cholesterol export process.

Thrombospondin proteins regulate vesicular trafficking of integrins and other membrane attachment complex proteins to the plasma membrane of skeletal muscle, which provides greater stability and resistance to muscular dystrophy.
