Cytoskeleton
Microfilaments
narrowest
Actin
most abundant protein in cells
grows and disassemble quickly
structure
double helix structure
threadlike structure
functions:
motility
tracks for protein movement(Myosin)
transport cargoes
signal transducer from outside to inside of the cell
directionality
size
7 nm in diameter
grow or shrink
Microtubules
tubulins
structure
globular monomeric proteins
hollow strand-like tube
largest
functions
cell division
directionality
resist compression forces
tracks for motor
grow or shrink
size
25 nm in diameter
Intermediate Filaments
keratin
nails
hair
skin
structure
multiple strands of fibrous proteins wound together
functions
mechanical strength
elastic properties
withstand tension
stable structures that form a true skeleton of the cell
examples

(muscle cells)
desmin filaments
size
8-10 in diameter
intermediate
