Secondary Information

Protein Function TTLL1 complex may be involved in tubulin substrate recognition, regulation of enzymatic activity, or subcellular localization
Biochemical Properties TTLL1 is a member of a large family of proteins with a TTL homology domain, whose members could catalyze ligations of diverse amino acids to tubulins or other substrates.The amino acid sequence of TTLL1 (PGs3) contains three conserved motifs that correspond to the adenosine triphosphate (ATP)/Mg2þ-binding site typical of enzymes with a carboxylateamine/thiol ligase activity, such as glutathione synthetase.

Additional Comments TTLL1 and TTL are members of a large family of conserved eukaryotic proteins with a TTL homology domain, which raises the possibility that other members of this family are also involved in polyglutamylation or other types of posttranslational amino acid ligations
