Chaperonin containing tailless complex polypeptide 1 (CCT) is a molecular chaperone consisting of eight distinct protein subunits, that when oligomeric is essential for the folding of newly synthesized tubulin and actin. In addition to folding, CCT activity includes functions of individual subunits in their monomeric form. For example, when CCTδ monomer levels are increased in cultured mammalian cells, numerous cell surface protrusions are formed from retraction fibres, indicating that an underlying function for the CCTδ monomer exists. Here, using a yeast two-hybrid screen we identify the dynactin complex component p150Glued as a binding partner for CCTδ and show by siRNA depletion that this interaction is required for the formation of CCTδ-induced cell surface protrusions. Intact microtubules are necessary for the formation of the protrusions, consistent with microtubule minus end transport driving the retraction fibre formation and depletion of either p150Glued or the dynactin complex-associated transmembrane protein dynAP prevents the previously observed localization of GFP-CCTδ to the plasma membrane. Wound healing assays reveal that CCTδ monomer levels influence directional cell migration and together our observations demonstrate that in addition to the folding activity of CCT in its oligomer form, a monomeric subunit is associated with events that involve the assembled cytoskeleton.
