Source	Description
Uniprot	TISSUE SPECIFICITY: Widely expressed at low level. Highly expressed in siliques. Weakly expressed in seedlings, young and mature leaves, cauline leaves, stems, flower buds and roots. {ECO:0000269\|PubMed:9839469}.

Functional Description ? help Back to Top
Source	Description
UniProt	Transcription repressor involved in regulation of protection against UV. Mediates transcriptional repression of CYP73A5, the gene encoding trans-cinnamate 4-monooxygenase, thereby regulating the accumulation of the UV-protectant compound sinapoylmalate. {ECO:0000269\|PubMed:11080161}.
