Binds to alpha-tubulin folding intermediates after their interaction with cytosolic chaperonin in the pathway leading from newly synthesized tubulin to properly folded heterodimer . Involved in regulation of tubulin heterodimer dissociation. May function as a negative regulator of axonal growth (By similarity).
Subcellular locations: Cytoplasm, Cytoplasm, Cytoskeleton
Colocalizes with microtubules. In differentiated neurons, located in the cytoplasm. In differentiating neurons, accumulates at the growth cone.
Found in most tissues.
