The 68,000-Dalton Neurofilament-Associated Polypeptide is a Component of Nonneuronal Cells and of Skeletal Myofibrils [PDF]

, 1980
Purified preparations of 10-nm neurofilaments from rat spinal cord and bovine or porcine brain contain a predominant 68,000-dalton polypeptide. This polypeptide is also a major component of the neurofilaments that copurify with brain tubulin isolated by ...

OCIAD2 Stabilizes Integrin β1 Signaling Through SNX17‐Mediated Endosomal Recycling to Lipid Rafts and Modulates Cisplatin Response in HNSCC

Advanced Science, EarlyView.
This study identifies OCIAD2 as a critical regulator of cisplatin resistance in HNSCC. Mechanistically, OCIAD2 stabilizes integrin β1 through a direct physical interaction and facilitates its SNX17‐dependent endosomal recycling to lipid raft microdomains. Targeting OCIAD2 disrupts integrin β1 trafficking and significantly enhances cisplatin sensitivity,
