Cap Z
Binds plus end of actin, prevents addition
Tropomodulin
Binds minus end, prevents removal
Tropomyosin
Stabilizes actin fibers
Cofilin
Forces actin fiber breakdown
Thymosin
Binds actin monomer, prevents addition
Profilin
Binds actin monomer increasing addition
G-actin
Monomer for actin
F-actin
Polymer for actin
Formin
Works with profilin, stabilizes G-actin, increases addition
Microtubule monomers
Alpha and beta tubulin
Gamma tubulin
Removes nucleation, place for dimers to add to
Microtubule GTPase
Beta tubulin
Kinesin-13
Slows addition, enduces catastrophe, destabilization of protofillament
XMAP215
Increases growth, slows catastrophe, stabilization of protofillament
Cillia/Flagella
Microtubules 9+2
Centrioles
Microtubules 9+0
Keratin (I& II)
Acid and base, give strength to epithelium, provide structure for hair, fingernails, scales
Vimentin III)
Widely expressed, creates junctions with other cells, involved in cell signalling
Neurofilaments (IV)
Help axon grow and strengthen it
Lamins (V)
In nucleus, can make a meshwork
Nestin (VI)
In axons, regulate axon width
