Molecular Motors

Hello, together, today we are talking about molecular motors. Molecular motors are cells of proteins with ATPAS or GTPAS activity, the organelles, proteins and other components of the cell move in all parts of the cell. Molecular motors are cellular proteins. They use energy through hydratization of ATP or GTP, to create power for a n B. Movements in a large n There are three superfamilies of molecular motors. These are kinasein, dinenine and myos. We will talk about each of these families in a minute. But first, let'start with kinasein. Kinasein is a double-headed molecule that moves its nucleus towards the plus end of microtubules. A head binds to the microtubules and then bends its neck, while the other head swings forward and binds, which creates almost continuous movement. Some kinasein molecules are both connected to the mitose and to the myos. Other kinaseins meet other functions, Kinaseins are often involved in anterior or front axonal transport. Next, we will deal with dinenine. Dinen have two heads, whose neck pieces are embedded in a complex protein. Dinen are involved in retrograde or reverse axonal transport. There are also different forms of dinen. First, we deal with the cytoplasmatic dinen. These behave There are also axonymidines, which drive the movement of the ciliate and flagrular. Then there is dynamine. Dynamine uses GTP and is involved in the endocytosis. The third molecular motor that we will now discuss is meosine. Meosine proteins are in different types, which are divided into 18 classes. The heads of the meosine molecules bind to actin and generate movement, by moving their neck regions in meosine two beams or along the microphilaments, one head after the other. This is seen in meosine 5. In this way, they fulfill different functions such as the contraction of muscles and the cell migration. Meosine heads have both affinity for actin and for ATP-ACtivity. About 300 meosine molecules are present in meosine filaments.
