HSF30 — Capsicum annuum

Summary

CaHSFA2 (HSF30) on pepper chromosome 7 encodes a heat stress transcription factor with HSF DNA-binding, winged helix-turn-helix DNA-binding superfamily, and winged helix-like DNA-binding superfamily domains. The product exhibits RNA polymerase II cis-regulatory region sequence-specific DNA binding, identical protein binding, and DNA-binding transcription factor activity. It is associated with cellular response to heat, defense response, ABA signaling, cell death, nuclear export, chromatin modeling, virus-induced PTGS, regulation of transcription by RNA polymerase II, and signal transduction. The protein localizes to both cytoplasm and nucleus. CaHSFA2 is linked to chlorophyll content. Studies of related genes in other species connect the HSF family to germination rate.
