Collagen receptor Collagen receptors are membrane proteins that bind the extracellular matrix protein collagen, the most abundant protein in mammals. They control mainly cell proliferation, migration and adhesion, coagulation cascade activation and they affect ECM structure by regulation of MMP (matrix metalloproteinases). There are at least eight human collagen receptors belonging to four different
Myosin like a dynamic tether, retaining vesicles and organelles in the actin-rich periphery of cells. A recent single molecule in vitro reconstitution study on assembling actin filaments suggests that Myosin V travels farther on newly assembling (ADP-Pi rich) F-actin, while processive runlengths are shorter on older (ADP-rich) F-actin. Myosin VI is an unconventional myosin motor, which is primarily processive as a dimer, but also acts as a nonprocessive monomer. It walks along actin filaments, travelling towards the pointed end (- end) of the filaments. Myosin VI is thought to transport endocytic vesicles into the cell. Myosin VII is an unconventional myosin
