MAPs (Tau, MAP2, MAP4 ) have two key domains:

1. Side-binding domains

2. Projection domains

#Unit 2. Cellular Organization

When stabilizing MAPs coat the outer wall of a microtubule, they can increase the growth rate of microtubules or reduce catastrophe frequency.

The activity of the MAPs is regulated by the reversible phosphorylation of their projection domains.
