Molecular Biology of the Cell
Directional cell migration drives embryonic development, cancer metastasis, and tissue repair and regeneration. Here, we examine the role of intraflagellar transport (IFT) 20 (Ift20) during polarized migration of epidermal cells. IFT20 is implicated

Arl/ARF GTPases regulate ciliary trafficking, but their tissue-specific functions are unclear. Here, we demonstrate that ciliary GTPase Arl3 is required for mitotic spindle orientation of mouse basal stem cells during skin development. Arl3 loss dimi

In the city that never sleeps, great science never takes a break. On 15 January 2016, the ‘New York Symposium on Quantitative Biology of the Cell’, a one-day local meeting of the American Society for Cell Biology (ASCB), took place at Columbia Un

Integrin endocytic recycling is critical for cell migration, yet how recycled integrins assemble into new adhesions is unclear. By synchronizing endocytic disassembly of focal adhesions (FAs), we find that recycled integrins reassemble FAs coincident

A new mechanism for focal adhesion disassembly is described involving microtubule-stimulated endocytosis of integrins at focal adhesions.
Focal adhesion disassembly is regulated by microtubules (MTs) through an unknown mechanism that involves dy

Hodgkin’s Lymphoma (HL) is one of the most prevailing malignancies in young adults. Reed–Sternberg (RS) cells in HL have distinctive large cell morphology, are characteristic of the disease and their presence is essential for diagnosis. Enlarged

Ciliogenesis in differentiating epidermal cells correlates with activation of Notch signaling, which requires Presenilin-2 targeting to basal bodies/cilia. Ezratty et al. show that the GTPase ARF4 regulates Presenilin-2 localization and subsequent No

Src kinase is a crucial mediator of adhesion-related signaling and motility. Src binds to focal adhesion kinase (FAK) through its SH2 domain and subsequently activates it for phosphorylation of downstream substrates. In addition to this binding funct
