HNF1 homeobox A (hepatocyte nuclear factor 1 homeobox A), also known as HNF1A, is a human gene.[1][2]

The protein encoded by this gene is a transcription factor that is highly expressed in the liver and is involved in the regulation of the expression of several liver specific genes.[3]



HNF1A has been shown to interact with PCAF,[7] Src,[7] RAC3,[7] EP300,[8] CREB binding protein[7] and PCBD1.[9][10]
