BZIP23

bZIP transcription factor 23

357 amino acids

Transcriptional activator that mediates abscisic acid (ABA) signaling (PubMed:18931143, PubMed:19947981, PubMed:27424498, PubMed:27325665). Can regulate the expression of a wide spectrum of stress-related genes in response to abiotic stresses through an ABA-dependent regulation pathway. Confers ABA-dependent drought and salinity tolerance (PubMed:18931143, PubMed:27325665). Binds specifically to the ABA-responsive elements (ABRE) in the promoter of target genes to mediate stress-responsive ABA signaling (PubMed:27325665, PubMed:27424498).

Belongs to the bZIP family. ABI5 subfamily.

BZIP23

Basic leucine zipper 23

249 amino acids

Transcription factor involved in the response to zinc ion deficiency. Binds to the consensus sequence 5'-[AG]TGTCGACA[CT]-3' also called zinc deficiency response element (ZDRE). The ZDRE sequence is conserved in the plant kingdom and present in the promoters of genes that constitute the primary response to zinc deficiency, comprising additional ZIP metal transporter genes (PubMed:20479230, PubMed:26306426). Required for zinc accumulation in roots. Mediates the expression of the zinc transporter ZIP12 during growth in zinc-deficient conditions. ZIP12 transporter is involved in zinc uptake in roots (PubMed:26306426).
