Hepatocyte nuclear factor 1, alpha isoform C-terminal (IPR006898)

Short name: HNF1a_C

Overlapping homologous superfamilies


Domain relationships



This domain consists of an alternative C terminus of homeobox-containing transcription factor HNF-1, found in the HNF-1A isoform. Different isoforms of HNF-1 are generated by the differential use of polyadenylation sites and by alternative splicing. The C-terminal region of HNF-1 is responsible for the activation of transcription, and HNF-1A, which has this C-terminal extension, transactivates less well than the B and C isoforms [PMID: 7900999]. Mutations and polymorphisms in HNF-1 cause the type 3 form of maturity-onset diabetes of the young (MODY3) [PMID: 9133564].
