What's a GeneRIF?

Data show that the group S1 basic leucine zipper transcription factors bZIP1 and bZIP53 reprogram primary C- and N-metabolism.
Title: Crosstalk between Two bZIP Signaling Pathways Orchestrates Salt-Induced Metabolic Reprogramming in Arabidopsis Roots.
promoters of these transient targets are uniquely enriched with cis-regulatory motifs coinherited with bZIP1 binding sites, suggesting a recruitment role for bZIP1.
Title: Hit-and-run transcriptional control by bZIP1 mediates rapid nutrient signaling in Arabidopsis.
Data indicate that transcription factors ANAC041, bZIP1 and MYB46 directly regulate the expression of CSLA9.
Title: Transcription factors that directly regulate the expression of CSLA9 encoding mannan synthase in Arabidopsis thaliana.
bZIP1 and bZIP53 expression is enhanced during dark-induced starvation. Heterodimerization with members of the partially redundant C/S1 bZIP factor network reprograms primary metabolism in the starvation response.
Title: Heterodimers of the Arabidopsis transcription factors bZIP1 and bZIP53 reprogram amino acid metabolism during low energy stress.
Data show that AtbZIP1 can bind ACGT-based motifs in vitro and that the binding characteristics appear to be affected by the heterodimerization between AtbZIP1 and the C-group AtbZIPs, including AtbZIP10 and AtbZIP63.
Title: The arabidopsis bZIP1 transcription factor is involved in sugar signaling, protein networking, and DNA binding.
