Protein: Tubulin polyglutamylase TTLL7 (EC 6.3.2.-) (Tubulin--tyrosine ligase-like protein 7) (mTTLL7) (A4Q9F0)
Organism: Mus musculus (Mouse)
Function: Polyglutamylase which modifies tubulin, generating polyglutamate side chains of variable lengths on the gamma-carboxyl group of specific glutamate residues within the C-terminal tail of tubulin. Mediates both ATP-dependent initiation and elongation steps of the polyglutamylation reaction. Preferentially modifies the beta-tubulin tail over an alpha-tail. Competes with monoglycylase TTLL3 for modification site on beta-tubulin substrate, thereby creating an anticorrelation between glycylation and glutamylation reactions (By similarity). Required for neurite growth; responsible for the strong increase in tubulin polyglutamylation during postnatal neuronal maturation.
Subcellular location: Cell projection, cilium {ECO:0000269|PubMed:16901895, ECO:0000269|PubMed:17499049}. Cytoplasm, cytoskeleton, cilium basal body {ECO:0000269|PubMed:16901895, ECO:0000269|PubMed:17499049}. Cell projection, dendrite {ECO:0000269|PubMed:16901895, ECO:0000269|PubMed:17499049}. Perikaryon {ECO:0000269|PubMed:16901895, ECO:0000269|PubMed:17499049}. Note=In cells with primary cilia, found in both cilia and basal bodies. In neuronal cells, found in dendrites and perikaryon. {ECO:0000269|PubMed:16901895, ECO:0000269|PubMed:17499049}.
