الوصف: | Myosin VI is involved in a wide range of endocytic and exocytic membrane trafficking pathways; clathrin-mediated endocytosis, intracellular transport of clathrin-coated and -uncoated vesicles, AP-1B-dependent basolateral sorting in polarized epithelial cells and secretion from the Golgi complex to the cell surface. In this study, using a yeast two-hybrid screen, we identified brain-enriched kinase/lemur tyrosine kinase 2 (BREK/LMTK2), a transmembrane serine/threonine kinase with previously unknown cellular functions, as a myosin VI-interacting protein. Several binding experiments confirmed the interaction of myosin VI with BREK in vivo and in vitro. Immunocytochemical analyses revealed that BREK localizes to cytoplasmic membrane vesicles and to perinuclear recycling endosomes. Notably, cells in which BREK was depleted by siRNA were still able to internalize transferrin molecules and to transport them to early endosomes, but were unable to transport them to perinuclear recycling endosomes. Our results show that BREK is critical for the transition of endocytosed membrane vesicles from early endosomes to recycling endosomes and also suggest an involvement of myosin VI in this pathway. |
