Dynamin 1 is important for microtubule organization and stabilization in glomerular podocytes.

Dynamin 1 is a neuronal endocytic protein that participates in vesicle formation by scission of invaginated membranes. Dynamin 1 is also expressed in the kidney; however, its physiological significance to this organ remains unknown. Here, we show that dynamin 1 is crucial for microtubule organization and stabilization in glomerular podocytes.

Internalization of AMPA-type Glutamate Receptor in the MIN6 Pancreatic β-cell Line.

The activity of AMPA-type glutamate receptor is involved in insulin release from pancreatic β-cells. However, the mechanism and dynamics that underlie AMPA receptor-mediated insulin release in β-cells is largely unknown. Here, we show that AMPA induces internalization of glutamate receptor 2/3 (GluR2/3), AMPA receptor subtype, in the mouse β-cell line MIN6.

[Corrigendum]Phosphorylation of cortactin by cyclin-dependent kinase 5 modulates actin bundling by the dynamin 1-cortactin ring-like complex and formation of filopodia and lamellipodia in NG108-15 glioma-derived cells.

Subsequently to the publication of the above article, the authors have realized that the second‑listed author, The Mon La, had not been properly credited as one of the co‑writers of the paper. Therefore, the Authors' Contributions of the Declarations section of the article should have read as follows: Authors' contributions HY, KTa and TML designed the research and wrote the paper. HY, TA, YM, EO and TT performed mutant protein construction, protein purification and actin bundling experiments.

Phosphorylation of cortactin by cyclin-dependent kinase 5 modulates actin bundling by the dynamin 1-cortactin ring-like complex and formation of filopodia and lamellipodia in NG108-15 glioma-derived cells.

Dynamin copolymerizes with cortactin to form a ring‑like complex that bundles and stabilizes actin filaments. Actin bundle formation is crucial for generation of filopodia and lamellipodia, which guide migration, invasion, and metastasis of cancer cells. However, it is unknown how the dynamin‑cortactin complex regulates actin bundle formation.
