Presentation transcript:

Motor Proteins Motor Protein A protein (as dynein, kinesin, or myosin) that moves itself along a filament or polymeric molecule using energy generated by the hydrolysis of ATP.

Types of motor proteins 1. Dynein 2. kinesin 3. myosin

Dynein Motor Protein -Dyneins are microtubule motors capable of a sliding movement. -Dynein complexes are much larger and more complex than kinesin and myosin motors. -Dynein facilitates the movement of cilia and flagella.

Dynein Motor Protein continued… -One type of Dynein motor protein is found in fungi. -Thirteen different types of Dynein motor proteins are found in insects. -Fourteen to Fifteen different Dynein motor proteins are found in humans. http://video.search.yahoo.com/search/video;_ylt=A0PDoTB9DuBONgkAtVqJzbkF?p=Dynein+protein+motor&fr=&fr=yfp-t-701-17&fr2=

Kinesin Motor Protein Flowering plants have an abundance of Kinesin Motor Proteins. Kinesin Motor Proteins specialize in the mitosis of plant cells.
