Tubulin polyglutamylase TTLL7 (Ttll7)

Polyglutamylase which preferentially modifies beta- tubulin (PubMed:16901895, PubMed:17499049, PubMed:19152315). Mediates both ATP-dependent initiation and elongation of polyglutamylation of microtubules (PubMed:16901895, PubMed:19152315).

Required for neurite growth; responsible for the strong increase in tubulin polyglutamylation during postnatal neuronal maturation (PubMed:16901895). .
