Polyglutamylase complex (Ttll1) polyglutamylates alpha subunits of tubulin
Polyglutamylase complex polyglutamylates alpha subunits of tubulin. The complex contains Ttll1 (Tubulin tyrosine ligase-like 1) protein. The complex has been isolated from mouse tissue and four additional protein components have been identified (Janke et al. 2005). A mouse mutation that disrupts one of these, Tpgs1, is associated with failure of polyglytamylation of alpha-chains in microtubules (Ikegami et al. 2007).
