AT1G32640 — Arabidopsis thaliana

Summary

AT1G32640 (JAI1, also known as MYC2, JIN1, and ZBF1) in Arabidopsis thaliana encodes a basic helix-loop-helix (bHLH) transcription factor of the MYC/MYB_N and AIB/MYC-like families. The gene product is associated with transcription corepressor and coactivator activities, RNA polymerase II cis-regulatory region sequence-specific DNA binding, and SUMO transferase activity. JAI1 is linked to defense gene expression, resistance to herbivory, ABA sensitivity, terpene biosynthesis, blue light-mediated photomorphogenic growth, phosphate deficiency response, and vein density. It is also associated with the regulation of secondary growth, chromatin looping, thermomorphogenesis, indole glucosinolate metabolism, and cellular response to sulfur starvation. The protein localizes to the nuclear ubiquitin ligase complex, mediator complex, and plasmodesmata. Related genes in other species are linked to chilling tolerance, fruit quality, and Botrytis cinerea resistance.
