This protein interacts with two glucocorticoid receptor coactivators, transcriptional intermediary factor 2 and steroid receptor coactivator 1. This protein may function as a coregulator of glucocorticoid receptor mediated gene induction and repression. This protein may also function as an alpha tubulin polyglutamylase.[provided by RefSeq, Feb 2010]. * **UniProt Summary**: Polyglutamylase which preferentially modifies alpha- tubulin. Involved in the side-chain initiation step of the polyglutamylation reaction rather than in the elongation step (By similarity). Required for CCSAP localization to both spindle and cilia microtubules. Increases the effects of NCOA2 in glucocorticoid receptor-mediated repression and induction and in androgen receptor-mediated induction (PubMed:17116691, PubMed:22493317). {ECO:0000250|UniProtKB:Q8CHB8, ECO:0000269|PubMed:17116691, ECO:0000269|PubMed:22493317}. |TTL| |protein polyglutamylation| |ligase activity| |peptidyl-glutamic acid modification| |retina development in camera-type eye| |cilium| |camera-type eye development| |microtubule| |eye development| |visual system development| |sensory system development| |centrosome| |sensory organ development| |peptidyl-amino acid modification| |ATP binding| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp120|Dimethyl-Sulfoxide 1pc R03 exp120]]|1.8| |[[:results:exp349|Cytochalasin-B 5μM R07 exp349]]|2.27| No correlation found to any other genes in chemogenomics.
