英文摘要Cyclin Y, a membrane associated cyclin, is capable of binding and activating CDK14. Here we report that human cyclin Y (CCNY) is a phosphoprotein in vivo and that phosphorylation of CCNY by CDK14 triggers its ubiquitination and degradation. Inactivation of either CDK14 or Cul1 results in accumulation of CCNY. An in vivo and in vitro mapping of CCNY phosphorylation sites by mass spectrometry revealed that the flanking regions of the conserved cyclin box are heavily phosphorylated. Phosphorylation of CCNY at Serines 71 and 73 creates a putative phospho-degron that controls its association with an SCF complex. Mutation of serine to alanine at these two sites stabilized CCNY and enhanced the activity of CCNY/CDK14 on phosphorylation of LRP6. Our results provide insight into autoregulation of the cyclin Y/CDK14 pair in CDK14 activation and cyclin Y turnover which is a process that is involved in membrane proximal signaling.
