A zinc-finger-type transcription factor WZF-1 that binds to a novel cis-acting element of histone gene promoters represses its own promoter.
WZF-1 is a zinc-finger protein which binds to the wheat histone gene promoter. Southwestern-binding analyses revealed that it bound a CACTC sequence, a novel positive cis-acting element. The activity of WZF-1 gene promoter, containing six CACTC sequences, was markedly reduced when WZF-1 was co-expressed, suggesting that WZF-1 is a transcriptional repressor.
