Functional Description

 Tubulin is the major constituent of microtubules. It binds two moles of GTP, one at an exchangeable site on the beta chain and one at a non-exchangeable site on the alpha chain (By similarity). 

Sequence Annotation

 NP_BIND 140 146 GTP (Potential).
 MOD_RES 172 172 Phosphoserine; by CDK1 (By similarity).
