| Primary Identifier | IPR046377 | Type | Family |
| Short Name | DHU1 |
| description | This is a plant family of proteins which includes DWD HYPERSENSITIVE TO UV-B 1 protein (DHU1) from Arabidopsis. DHU1 may act as a substrate receptor of a CUL4-RING E3 ubiquitin-protein ligase (CRL4) complex involved in the negative regulation of cellular responses to ultraviolet-B (UV-B) illumination, likely in coordination with RUP1 [, ]. It interacts with COP1 and probably prevents the formation of active UVR8-COP1 complex, thus avoiding UVR8-COP1-mediated positive regulation of UV-B responses []. |
