Light and the E3 ubiquitin ligase COP1/SPA control the protein stability of the MYB transcriptions factors PAP1 and PAP2 involved in anthocyanin accumulation in Arabidopsis.
Anthocyanins are natural pigments that accumulate only in light-grown and not in dark-grown Arabidopsis plants. Repression of anthocyanin accumulation in darkness requires the COP1/SPA ubiquitin ligase since cop1 and spa mutants produce anthocyanins also in darkness. Here, we show that COP1 and SPA proteins interact with the MYB transcription factors PAP1 and PAP2, two members of a small protein family ... [more]

| PAP1 SPA1 | Affinity Capture-Western Affinity Capture-Western An interaction is inferred when a bait protein is affinity captured from cell extracts by either polyclonal antibody or epitope tag and the associated interaction partner identified by Western blot with a specific polyclonal antibody or second epitope tag. This category is also used if an interacting protein is visualized directly by dye stain or radioactivity. Note that this differs from any co-purification experiment involving affinity capture in that the co-purification experiment involves at least one extra purification step to get rid of potential contaminating proteins. | Low | - | BioGRID | - |
