HNF1B

HNF1B is a member of the homeodomain-containing superfamily of transcription factors. HNF1B binds to DNA as either a homodimer, or a heterodimer with the related protein hepatocyte nuclear factor 1-alpha. HNF1B has been shown to function in nephron development, and regulates development of the embryonic pancreas. Mutations in HNF1B result in renal cysts and diabetes syndrome and noninsulin-dependent diabetes mellitus, and expression of HNF1B is altered in some types of cancer.

Full Name

HNF1 Homeobox B

Function

Transcription factor that binds to the inverted palindrome 5'-GTTAATNATTAAC-3' (PubMed:7900999, PubMed:17924661).

Binds to the FPC element in the cAMP regulatory unit of the PLAU gene (By similarity).

Transcriptional activity is increased by coactivator PCBD1 (PubMed:24204001).

Involvement in disease

Renal cysts and diabetes syndrome (RCAD):
An autosomal dominant disorder comprising non-diabetic renal disease resulting from abnormal renal development, and diabetes, which in some cases occurs earlier than age 25 years and is thus consistent with a diagnosis of maturity-onset diabetes of the young (MODY5). The renal disease is highly variable and includes renal cysts, glomerular tufts, aberrant nephrogenesis, primitive tubules, irregular collecting systems, oligomeganephronia, enlarged renal pelves, abnormal calyces, small kidney, single kidney, horseshoe kidney, and hyperuricemic nephropathy. Affected individuals may also have abnormalities of the genital tract.
Diabetes mellitus, non-insulin-dependent (NIDDM):
A multifactorial disorder of glucose homeostasis caused by a lack of sensitivity to the body's own insulin. Affected individuals usually have an obese body habitus and manifestations of a metabolic syndrome characterized by diabetes, insulin resistance, hypertension and hypertriglyceridemia. The disease results in long-term complications that affect the eyes, kidneys, nerves, and blood vessels.
Prostate cancer, hereditary, 11 (HPC11):
A condition associated with familial predisposition to cancer of the prostate. Most prostate cancers are adenocarcinomas that develop in the acini of the prostatic ducts. Other rare histopathologic types of prostate cancer that occur in approximately 5% of patients include small cell carcinoma, mucinous carcinoma, prostatic ductal carcinoma, transitional cell carcinoma, squamous cell carcinoma, basal cell carcinoma, adenoid cystic carcinoma (basaloid), signet-ring cell carcinoma and neuroendocrine carcinoma.
