Function

[TBA1B_BOVIN] 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. [STMN4_RAT] Exhibits microtubule-destabilizing activity.^[1] ^[2] ^[3] [TBB2B_BOVIN] 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).

Publication Abstract from PubMed

Tubulin tyrosine ligase (TTL) catalyzes the post-translational retyrosination of detyrosinated alpha-tubulin. Despite the indispensable role of TTL in cell and organism development, its molecular mechanism of action is poorly understood. By solving crystal structures of TTL in complex with tubulin, we here demonstrate that TTL binds to the alpha and beta subunits of tubulin and recognizes the curved conformation of the dimer. Biochemical and cellular assays revealed that specific tubulin dimer recognition controls the activity of the enzyme, and as a consequence, neuronal development. The TTL-tubulin structure further illustrates how the enzyme binds the functionally crucial C-terminal tail sequence of alpha-tubulin and how this interaction catalyzes the tyrosination reaction. It also reveals how TTL discriminates between alpha- and beta-tubulin, and between different post-translationally modified forms of alpha-tubulin. Together, our data suggest that TTL has specifically evolved to recognize and modify tubulin, thus highlighting a fundamental role of the evolutionary conserved tubulin tyrosination cycle in regulating the microtubule cytoskeleton.
