CC -!- FUNCTION: Probable tubulin polyglutamylase that generates side chains
CC of glutamate on the gamma-carboxyl group of specific glutamate residues
CC within the C-terminal tail of target proteins. Similar to TTLL1, may
CC acquire enzymatic activity only in complex with other proteins as it is
CC most likely lacking domains important for autonomous activity. Mediates
CC tubulin polyglutamylation which induces establishment of microtubule
CC heterogeneity in sperm flagella, thereby playing a role in normal
CC motile flagella axoneme structure and sperm flagella beating pattern.
CC {ECO:0000250|UniProtKB:A2APC3}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=(L-glutamyl)(n)-gamma-L-glutamyl-L-glutamyl-[protein] + ATP +
CC L-glutamate = (L-glutamyl)(n+1)-gamma-L-glutamyl-L-glutamyl-[protein]
CC + ADP + H(+) + phosphate; Xref=Rhea:RHEA:60148, Rhea:RHEA-COMP:15519,

CC PhysiologicalDirection=left-to-right; Xref=Rhea:RHEA:60149;
CC Evidence={ECO:0000250|UniProtKB:A2APC3};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000250|UniProtKB:A4Q9E8};
CC -!- SUBCELLULAR LOCATION: Cytoplasm, cytoskeleton, cilium basal body
CC {ECO:0000250|UniProtKB:A2APC3}. Cytoplasm, cytoskeleton
CC {ECO:0000250|UniProtKB:A2APC3}. Cytoplasm, cytoskeleton, flagellum
CC axoneme {ECO:0000250|UniProtKB:A2APC3}.
CC -!- DOMAIN: Gln-155 is the main determinant for regioselectivity, which
CC segregates between initiases and elongases in all tubulin--tyrosine
CC ligase family. A glutamine residue at this position is found in
CC elongases TTLL6, TTLL9, TTLL11, TTLL13, TTLL10 and favors glutamate-
CC chain elongation, whereas an arginine residue is found in initiases
CC TTLL2, TTLL4, TTLL5, TTLL3, TTLL8 and favors initiation.
CC {ECO:0000250|UniProtKB:A4Q9E8}.
CC -!- SIMILARITY: Belongs to the tubulin--tyrosine ligase family.
CC {ECO:0000305}.
