Transcription factor that binds specifically to the RAS-responsive elements (RRE) of gene promoters (PubMed:9305772, PubMed:15067362, PubMed:8816445, PubMed:10390538, PubMed:17550981). Represses the angiotensinogen gene (PubMed:15067362). Negatively regulates the transcriptional activity of AR (PubMed:17550981). Potentiates the transcriptional activity of NEUROD1 (PubMed:12482979). Promotes brown adipocyte differentiation (By similarity). May be involved in Ras/Raf-mediated cell differentiation by enhancing calcitonin expression (PubMed:8816445). Interacts with NEUROD1 (PubMed:12482979). Interacts with AR (PubMed:17550981). Expressed in heart, placenta, lung, liver, skeletal muscle, kidney and pancreas. Not found in the brain. Belongs to the krueppel C2H2-type zinc-finger protein family. Truncated N-terminus. Contaminating sequence. Potential poly-A sequence. Numerous sequencing errors.
