Flashcards in Microtubule Accessory Proteins Deck (12):
1

Stathmin

Binds tubulin subunits stops them form assembling

2

gamma (y)-TuRC

Is concentrated in the centrosome.

3

Centrisome

Has the centrioles within it
pericentriolar material outside
Ringed with gamma - TuRC

4

+TIPs

Remains associated with the growing plus end and can link them to others structures such as membranes. This allows the microtubule to still grow and push off or push a structure

5

XMAP215

XMAP215 accelerates growth of + end of the microtubule by stabilizing it through binding

6

MAPs

Stabilizes the whole microtubule by binding along its sides.

7

Katanin

Severs microtubules like a katana!

8

Plectin

Links intermediate filaments to microtubules

9

Kinesin-13

causes catastrophe for microtubules

10

Tau

links with microtubules in a close proximity. It is only in the axon

11

MAP2

Binds in a spread out fashion and exists in the soma and dendrites

12

EB1 protein

Is a capping protein that binds with Kar9 protein.
