Dynein in cilia
WebThe DNAI1 gene provides instructions for making a protein that is part of a group (complex) of proteins called dynein. This complex functions within cell structures called cilia. Cilia are microscopic, finger-like projections that stick out from the surface of cells. Coordinated back and forth movement of cilia can move the cell or the fluid ... WebDynein is a minus-end-directed microtubule motor protein, which transports a variety of intracellular cargo by hydrolysing ATP to power its movement along …
