RT   "Cofactor A is a molecular chaperone required for beta-tubulin folding:
RT   functional and structural characterization.";
RL   Biochemistry 35:10422-10435(1996).
CC   -!- FUNCTION: Tubulin-folding protein; involved in the early step of the
CC       tubulin folding pathway.
CC   -!- SUBUNIT: Supercomplex made of cofactors A to E. Cofactors A and D
CC       function by capturing and stabilizing tubulin in a quasi-native
CC       conformation. Cofactor E binds to the cofactor D-tubulin complex;
CC       interaction with cofactor C then causes the release of tubulin
CC       polypeptides that are committed to the native state.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm, cytoskeleton.
CC   -!- SIMILARITY: Belongs to the TBCA family. {ECO:0000305}.
