Handles Oxidative stress in the body.
Molecular motor that takes cargo to center of cell
Turn things off
Stabilizes microtubules, blocking cell division
The folded bits in the mitochondria

Binds and hydrolyzes GTP
Shuttle that promotes nucleotide exchange
What is IP3?

Rate of using ATP
Any device that changes some measurable quantity into another measurable quantity
Portion that is connected to filament
