| Plant Specific |
No |
| Functional Domains |
Protein-protein interacting domain |
| Must-have InterProScan Domain Pattern |
IPR011525 |
| Prohibited InterProScan Domain Pattern |
IPR010525 IPR003340 |
| Description |
AUX?CIAA proteins did not have any DNA binding domain. It has only domain III and IV which are also present ARF group of transcription factors. This domains work as a protein-protein interacting domain. In absence of auxin, AUX-IAA sequester ARF by protein-protein interaction and inhibit it from DNA binding. Upon precision of auxin by plant cells it promotes AUX-IAA degradation only after that ARF can bind to DNA.
