| Function: | |
Serine protease that degrades the two-component response regulator ARR4 (PubMed:27274065, PubMed:29180814). Regulates ARR4 stability by targeting ARR4 in the nucleus for degradation. Acts upstream of ARR4 and regulates the activity of ARR4 in cytokinin and light-signaling pathways. ARR4 mediates the cross-talk between light and cytokinin signaling through modulation of the activity of phytochrome B (PubMed:27274065). {ECO:0000269|PubMed:27274065, ECO:0000269|PubMed:29180814}. |
|
||
| Subunit: | |
Homooctamer formed by 4 homodimers (PubMed:29180814). Interacts with ARR4 (PubMed:27274065). {ECO:0000269|PubMed:27274065, ECO:0000269|PubMed:29180814}. |
| Subcellular location: | |
Nucleus {ECO:0000269|PubMed:27274065}. |
| Tissue specificity: | |
Expressed in roots, cotyledons, rosette leaves, cauline leaves, stems, flowers and siliques. {ECO:0000269|PubMed:27274065}. |
