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.

Kinesin Motor ProteinFlowering plants have an abundance of Kinesin Motor Proteins.

Kinesin Motor Proteins specialize in the mitosis of plant cells.
