Protein
Ninja-family protein MODD
Organism
Oryza sativa subsp. japonica
Function
Acts as negative regulator of abscisic acid (ABA) signaling and drought tolerance. Mediates deactivation and degradation of BZIP46, a positive regulator of ABA signaling and drought stress tolerance. Represses BZIP46 activity via interaction with the TPR3-HDAC1 corepressor complex and down-regulation of the histone acetylation level at BZIP46 target genes. Promotes BZIP46 degradation via interaction with the U-box type ubiquitin E3 ligase PUB70.
Similarity
Belongs to the Ninja family.
