CC   -!- FUNCTION: Acts to sequester alpha-tubulin from interaction with beta-
CC       tubulin, raising the possibility that it plays a regulatory role in the
CC       formation of the tubulin heterodimer.
CC   -!- SUBUNIT: Binds to monomeric alpha-tubulin.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm. Cytoplasm, cytoskeleton.
CC       Note=Microtubule-associated.
CC   -!- MISCELLANEOUS: Present with 656 molecules/cell in log phase SD medium.
CC       {ECO:0000269|PubMed:14562106}.
CC   -!- SIMILARITY: Belongs to the TBCB family. {ECO:0000305}.
