'''HNF1 homeobox B''' (hepatocyte nuclear factor 1 homeobox B), also known as '''HNF1B''' or '''transcription factor 2''' ('''TCF2'''), is a human [[gene]].

== Function ==

TCF2 encodes transcription factor 2, a protein of the homeobox-containing basic helix-turn-helix family. The TCF2 protein is believed to form heterodimers with another member of this transcription factor family, TCF1; depending on the TCF2 isoform, the result may be to activate or inhibit transcription of target genes.Deficiency of TCF2 cause abnormal maternal-Zygote transition and early embryogenesis failure.<ref>{{cite journal |vauthors=Barbacci E, Reber M, Ott MO, etal | year = 1999 |title = Variant hepatocyte nuclear factor 1 is required for visceral endoderm specification |  journal = Development | volume = 126 | issue = | pages = 4795–4805 }}</ref><ref>{{cite journal |vauthors=Coffinier C, Thepot D, Babinet C, etal | year = 1999 | title = Essential role for the homeoprotein vHNF1/HNF1beta in visceral endoderm differentiation |  journal = Development | volume = 126 | issue = | pages =  4785–4794 }}</ref><ref name="pmid28794155">{{cite journal | vauthors = Zhang J, Qu P, Zhou C | title = MicroRNA-125b is a key epigenetic regulatory factor that promotes nuclear transfer reprogramming | journal = The Journal of Biological Chemistry | volume = 292 | issue = 38 | pages = 15916–15926 | date = Sep 2017 | pmid = 28794155 | pmc = 5612121 | doi = 10.1074/jbc.M117.796771 }}</ref> Mutation of TCF2 that disrupts normal function has been identified as the cause of MODY5 ([[Maturity-Onset of Diabetes]], Type 5).
