The protein encoded by this gene is a zinc finger
transcription factor that binds to RAS-responsive elements (RREs)
of gene promoters. It has been shown that the calcitonin gene
promoter contains an RRE and that the encoded protein binds there
and increases expression of calcitonin, which may be involved in
Ras/Raf-mediated cell differentiation. Multiple transcript variants
encoding several different isoforms have been found for this gene.
