Comment typeDescription
Alternative ProductsEvent=Alternative splicing; Named isoforms=2; Name=1; IsoId=Q9SPG2-1; Sequence=Displayed; Name=2; IsoId=Q9SPG2-2; Sequence=VSP_042252; Note=Derived from EST data. No experimental confirmation available.;
Developmental StageFirst present in stems, petioles and the main veins of true leaves in young seedlings. Later accumulates in leaves and present in lateral roots. During transition from the vegetative to the generative stage, preferentially expressed in inflorescence. {ECO:0000269|PubMed:17521412}.
Disruption PhenotypeLow levels of aliphatic glucosinolates and decreased repressing effect of brassinosteroid on glucosinolates. {ECO:0000269|PubMed:23580754}.
FunctionMajor regulator of short-chained aliphatic glucosinolates (GLSs) biosynthesis. Together with MYB29/HAG3 and MYB76/HAG2, promotes aliphatic glucosinolate biosynthesis but represses indolic glucosinolate biosynthesis. Prevents insect performance (e.g. lepidopteran insect Mamestra brassicae and Spodoptera exigua) by promoting glucosinolates. {ECO:0000269|PubMed:17420480, ECO:0000269|PubMed:17521412, ECO:0000269|PubMed:18042203, ECO:0000269|PubMed:18446225, ECO:0000269|PubMed:20348214, ECO:0000269|PubMed:23580754, ECO:0000269|PubMed:23792303, ECO:0000269|PubMed:23943862}.
InductionSlightly induced by glucose, gibberellic acid (GA), jasmonic acid (JA) and salicylic acid (SA). Transiently induced in inflorescence by mechanical stimuli such as touch or wounding, including herbivory-wounding. Up-regulated by sulfur-deficient stress. {ECO:0000269|PubMed:16463103, ECO:0000269|PubMed:17521412, ECO:0000269|PubMed:23115560, ECO:0000269|PubMed:23792303}.
SimilarityContains 2 HTH myb-type DNA-binding domains. {ECO:0000255|PROSITE-ProRule:PRU00625}.
Subcellular LocationNucleus {ECO:0000255|PROSITE- ProRule:PRU00625, ECO:0000269|PubMed:17521412}.
SubunitCan form complexes with MYC2, MYC3 or MYC4.
Tissue SpecificityExpressed in generative organs, mature leaves and trichomes. {ECO:0000269|PubMed:17521412, ECO:0000269|PubMed:23115560}.
