Unformatted text preview: Functions Anchor for other cell components, particularly the nucleus Are important in cell attachments (desmosomes) Reinforce cells under tension, maintaining shape. Form the nuclear lamina (a layer beneath the nuclear envelope) Locomotion and the Cytoskeletal System Motor Proteins Most cellular locomotion is generated by motor proteins that associate with cytoskeleton microfilaments or microtubules. Myosin is a motor protein that works with actin microfilaments in muscle contraction. Two other motor proteins, dyenin and kinesin generate locomotion along microtubules for vesicle and organelle transport. Motor proteins use energy to generate movement. This energy supply is provided by phosphates from the energy molecule, ATP....
