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 the retina and cochlea. Myosin IV has a single IQ motif and a tail that lacks any coiled-coil forming sequence. It has homology similar to the tail domains of Myosin VII and XV. Myosin V is an unconventional myosin motor, which is processive as a dimer and has a step size of 36 nm. It translocates (walks) along actin filaments traveling towards the barbed end (+ end) of the filaments. Myosin V is involved in the transport of cargo (e.g. RNA, vesicles, organelles, mitochondria) from the center of the cell to the periphery, but has been furthermore shown to act
