BZIP60 — Arabidopsis thaliana

Summary

AT1G42990, designated BZIP60, encodes a basic region/leucine zipper (bZIP) transcription factor with DNA-binding and histone H3 methylase activity. The protein localises to the endoplasmic reticulum membrane and nucleus. BZIP60 is associated with the unfolded protein response, protein folding in the ER, macroautophagy, plastid gene expression, and cellular responses to salt stress. It is linked to immune system processes, simple leaf morphogenesis, and organ growth. The gene is associated with temperature stress response, seed maturation and dormancy, flowering time, root length and thickness, vegetative growth time, disease tolerance, photochemical quenching, and stomatal closure. Associations with thermotolerance, salt stress tolerance, fungal pathogen resistance, and ER stress resolution have been observed. BZIP60 is related to BZIP17 and BZIP28, and related genes in other species are linked to cold tolerance.
