BZIP17

Gene
BZIP17
Protein
bZIP transcription factor 17
Organism
Arabidopsis thaliana
Length
721 amino acids
Function
Transcriptional activator involved in salt and osmotic stress responses. Functions as a stress sensor and transducer in a signaling pathway that resembles an ER stress response. Following salt stress, BZIP17 is cleaved by SBT6.1 (S1P) and S2P at the C-terminus and the N-terminal bZIP component is translocated to the nucleus, where it activates the expression of salt stress response genes (PubMed:17662035). Functions as a stress sensor and transducer in ER stress signaling pathway. ER stress induces proteolysis of BZIP17 by SBT6.1 (S1P) and S2P, and the N-terminal bZIP component is translocated to the nucleus, where it activates the expression and production of ER chaperones, as well as protein involved in brassinosteroid (BR) signaling, which is required for stress acclimation and growth (PubMed:20876872).
Similarity
Belongs to the bZIP family.
