Basic information
Locus name	AT3G55530
Alias	SDIR1
Organism	Arabidopsis thaliana
Taxonomic identifier	[NCBI]
Function category	Protein degradation/modification: E3 ligase
Effect for Senescence	Unclear
Gene Description	Encodes an intracellular membrane localized protein with E3 ligase activity that is involved in regulation of ABA signaling. Loss of function alleles show decreased sensitivity to ABA. Overexpression results in increased sensitivity to ABA.
Evidence	Genomic evidence:microarray data [Ref 1]
