CUE domain found in CUE domain-containing protein 2 (CUED2) and similar proteins
CUEDC2 is a novel negative regulator of progesterone receptor (PR) and functions to promote the progesterone-induced PR degradation by the ubiquitin-proteasome pathway. It also acts as the regulator of JAK1/STAT3 signaling through inhibiting cytokine-induced phosphorylation of JAK1 and STAT3 and the subsequent STAT3 transcriptional activity. All members in this subfamily contain a CUE domain.
