Document Summary
These include: cytoplasmic dynein & kinesin family members. Secretory vesicles are carried by kinesins (the kinetic molecule). Cells can regulate this type of transport by choosing when they want to bring things in an. Transport can be activated or inhibited by signaling molecules. Dispersing melanosomes in melanocytes will increase pigmentation of the skin & this is c cyclical amp that allows proteins to carry these molecules outward toward the periphery. The melanosomes aggregate with low cyclical amp because they can"t be transported. n and bring things out. is caused by high hery of the cell. Is a motor protein that walks to the microtubule + end using its head domains. Head domains form a dimer that is connected to a coil that leads to the light chain polypeptide chain. The coil has a break in it in the middle. The light chain has an atp binding pocket and binding site & produces energy for motion hydrolysis.
