Tubulin folding cofactor C （TBCC） is a member of the TBCC family. TBCC has a role in the control of centrosome and Golgi apparatus positioning， with effects on cell shape and cell migration. Cofactor C is 1 of 4 proteins （cofactors A，D，E and C） engaged in the pathway leading to properly folded b-tubulin from folding intermediates. Cofactor E attaches to the cofactor D/beta-tubulin complex； their interaction with cofactor C subsequently causes the release of beta-tubulin polypeptides which are bound to the native state.
