tubulin chaperone complex

Function: - folding of tubulin - TBCA & TBCD function by capturing & stabilizing tubulin in a quasi-native conformation - TBCE binds to TBCD-tubulin complex - interaction with TBCC then causes release of tubulin polypeptides committed to the native state Structure: - consists of: TBCA, TBCB, TBCC, TBCD, TBCE
