Physcomitrella patens ARF Family
Description
Guilfoyle et al. 1998: Auxin response factors or ARFs are a recently discovered family of transcription factors that bind with specificity to auxin response elements (AuxREs) in promoters of primary or early auxin-responsive genes. ARFs have an amino-terminal DNA-binding domain related to the carboxyl-terminal DNA-binding domain in the maize transactivator VIVIPAROUS1. All but one ARF identified to date contain a carboxyl-terminal protein-protein interaction domain that forms a putative amphipathic alpha-helix. A similar carboxyl-terminal protein-protein interaction domain is found in the Aux/IAA class of auxin-inducible proteins. Some ARFs contain transcriptional activation domains, while others contain repression domains. ARFs appear to play a pivotal role in auxin-regulated gene expression of primary response genes.
Members of this familySHOULD possess Auxin_resp domain
Benchmark against A. thaliana
The Sensitivity and Positive Predictive Value (PPV) were assessed for this family. The data reported by Remington et al. 2004 for A. thaliana were taken as gold standard.
The gold standard reported 23 members for this family, 21 of which are present in ArabTFDB, giving a PPV of 0.95. Two additional members not present in ArabTFDB might be false negatives, giving a Sensitivity of 0.91.
This family is also present in:
- Selaginella moellendorffii
- Oryza sativa subsp. indica
- Oryza sativa subsp. japonica
- Sorghum bicolor
- Zea mays
- Arabidopsis lyrata
- Arabidopsis thaliana
- Carica papaya
- Populus trichocarpa
- Vitis vinifera
There are 13 gene models in this family
