hepatocyte nuclear factor 1


Summary: A transcription factor and homeodomain protein that regulates the expression of a large set of hepatic proteins including SERUM ALBUMIN; beta-fibrinogen; and ALPHA 1-ANTITRYPSIN. It is composed of hetero- or homo-dimers of HEPATOCYTE NUCLEAR FACTOR 1-ALPHA and HEPATOCYTE NUCLEAR FACTOR 1-BETA.
