||
| Function: | |
Functions as soluble gibberellin (GA) receptor. GA is an essential hormone that regulates growth and development in plants. Binds with high affinity the biologically active GAs such as GA1, GA3 and GA4, but has low or no affinity for the biologically inactive GAs. Upon GA-binding, it interacts with the DELLA protein SLR1, a repressor of GA signaling. This leads to SLR1 degradation by the proteasome, allowing the GA signaling pathway. {ECO:0000269|PubMed:16193045}. |
|
||
| Subunit: | |
Interacts with the DELLA protein SLR1 in a GA-dependent manner, resulting in subsequent SLR1 degradation. {ECO:0000269|PubMed:16193045, ECO:0000269|PubMed:19037316, ECO:0000269|PubMed:24131983}. |
| Subcellular location: | |
Nucleus {ECO:0000269|PubMed:16193045}. |
| Disruption phenotype: | |
Severe dwarf phenotype with wide and dark-green leaf blades. Plants insensitive to gibberellic acid (GA). {ECO:0000269|PubMed:16193045}. |
| Similarity: | |
Belongs to the 'GDXG' lipolytic enzyme family. {ECO:0000305}. |
