Putative transcription factor that appears to regulate lipid metabolism. New Zealand obese (NZO) mice carry a loss-of-function mutation due to the integration of the retrotransposon IAPLTR1 in intron 3 which generates a truncated mRNA lacking both the KRAB and the C2H2 domains. This strain is less diabetes prone (NZO). Belongs to the krueppel C2H2-type zinc-finger protein family.
