Arabidopsis STO/BBX24 negatively regulates UV-B signaling by interacting with COP1 and repressing HY5 transcriptional activity ... BBX24 expression is UV-B-inducible and its accumulation under UV-B requires COP1 Gangappa et al., Plant Cell 2013

Moreover, genetic relationships of bbx25 and bbx24 with hy5 and cop1 revealed that BBX25 and BBX24 additively enhance COP1 and suppress HY5 functions
