HSFB3 — Phaseolus vulgaris

Summary

PHAVU_001G131000, symbol HSFB3, encodes a protein with an HSF-type DNA-binding domain. The PvHSFB3 protein 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, regulation of transcription by RNA polymerase II, cell death, and DNA-dependent transcription. The protein localises to both the cytoplasm and nucleus. Related genes in other species are linked to seed weight, plant height, and arsenic concentration traits, though these associations are not yet established in French bean.
