This process is triggered by p34CDC28-dependent phosphorylation of Cln3. Here we demonstrate that the molecular chaperone Ydj1, a DnaJ homolog, is required for this phosphorylation. In a ydj1 mutant at the nonpermissive temperature, both phosphorylation and degradation of Cln3 were deficient. No change was seen upon inactivation of Sis1, another DnaJ homolog. The phosphorylation defect in the ydj1 mutant was specific to Cln3, because no reduction in the phosphorylation of Cln2 or histone H1, which also requires p34CDC28, was observed. Ydj1 was required for Cln3 phosphorylation and degradation rather than for the proper folding of this cyclin, since Cln3 produced in the ydj1 mutant was fully active in the stimulation of p34CDC28 histone kinase activity. Moreover, Ydj1 directly associates with Cln3 in close proximity to the segment that is phosphorylated and signals degradation. Thus, binding of Ydj1 to this domain of Cln3 seems to be essential for the phosphorylation and breakdown of this cyclin. In a cell-free system, purified Ydj1 stimulated the p34CDC28-dependent phosphorylation of the C-terminal segment of Cln3 and did not affect phosphorylation of Cln2 (as was found in vivo). The reconstitution of this process with pure components provides evidence of a direct role for the chaperone in the phosphorylation of Cln3."xsd:string |
