Involved in the side-chain initiation step of the polyglutamylation reaction rather than in the elongation step. Involved in formation of short side-chains. Mediates initiation of polyglutamylation of nucleosome assembly proteins NAP1L1 and NAP1L4. Also acts as a monoglutamylase: generates monoglutamylation of CGAS, leading to impair the nucleotidyltransferase activity of CGAS. {ECO:0000250|UniProtKB:Q80UG8}. |TTL| |protein-glutamic acid ligase activity| |protein polyglutamylation| |peptidyl-glutamic acid modification| |tubulin binding| |cilium| |microtubule| |peptidyl-amino acid modification| |ATP binding| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp483|FTY720 3μM R08 exp483]]|1.7| No correlation found to any other genes in chemogenomics.
