Myosin as a person with longer legs can move farther with each individual step. The velocity of a myosin motor depends upon the rate at which it passes through a complete kinetic cycle of ATP binding to the release of ADP. Myosin I, a ubiquitous cellular protein, functions as monomer and functions in vesicle transport. It has step size of 10 nm and has been implicated as being responsible for the adaptation response of the stereocilia in the inner ear. Myosin II (also known as conventional myosin) is the myosin type responsible for producing muscle contraction in muscle cells. In muscle
Collagen receptor N-terminal domain rich in cystein, F2 fibronectin type II domain and several C-lectin domains. From this mannose family, collagen is specifically bound by mannose receptor, M-phospholipase A2 receptor and Endo180 receptor. Binding of collagen or denatured collagen (gelatin) is provided by F2 domain and partly by C-terminal domain (aa 1000-1453), which binds type I collagen triple helix. Inability to internalize collagen and reduced ability of adhesion and related increased migration in collagen matrix was observed in fibroblast population with nonfunctional Endo180 receptor. The exact principal of collagen binding to mannose receptor is not known so far. Endo180 receptor is expressed
