VIP and PGE2 rapidly activate protein kinase A (PKA) that then phosphorylates NKD2 at Ser-223, a process that is facilitated by the molecular scaffold A-kinase anchoring protein 12 (AKAP12). This phosphorylation stabilized NKD2, ensuring efficient cell-surface delivery of TGFα and increased EGFR activation. |

Here, we show that Naked2 is a short-lived protein with a half-life of 60 min caused by its rapid ubiquitin-mediated proteasomal degradation. Overexpression of TGF-alpha stabilizes Naked2 protein in an EGF receptor (EGFR)-independent manner; a physical interaction between the cytoplasmic tail of TGF-alpha and Naked2 is necessary and sufficient for this protection. We have identified a RING finger protein, AO7/RNF25, as a ubiquitin ligase for Naked2, and we have shown that overexpression of TGF-alpha reduces binding of AO7 to Naked2. |
