CC   -!- FUNCTION: Activates insulin, somatostatin, glucokinase, islet amyloid
CC       polypeptide and glucose transporter type 2 gene transcription.
CC       Particularly involved in glucose-dependent regulation of insulin gene
CC       transcription. As part of a PDX1:PBX1b:MEIS2b complex in pancreatic
CC       acinar cells is involved in the transcriptional activation of the ELA1
CC       enhancer; the complex binds to the enhancer B element and cooperates
CC       with the transcription factor 1 complex (PTF1) bound to the enhancer A
CC       element. Binds preferentially the DNA motif 5'-[CT]TAAT[TG]-3'. During
CC       development, specifies the early pancreatic epithelium, permitting its
CC       proliferation, branching and subsequent differentiation. At adult
CC       stage, required for maintaining the hormone-producing phenotype of the
CC       beta-cell.
CC   -!- SUBUNIT: Interacts with the basic helix-loop-helix domains of TCF3(E47)
CC       and NEUROD1 and with HMG-I(Y). Interacts with SPOP (By similarity).
CC       Interacts with the methyltransferase SETD7. Part of a PDX1:PBX1b:MEIS2b
CC       complex. {ECO:0000250, ECO:0000269|PubMed:16141209}.
CC   -!- SUBCELLULAR LOCATION: Nucleus. Cytoplasm, cytosol {ECO:0000250}.
CC   -!- TISSUE SPECIFICITY: Duodenum and pancreas (Langerhans islet beta cells
CC       and small subsets of endocrine non-beta-cells, at low levels in acinar
CC       cells).
CC   -!- DOMAIN: The Antp-type hexapeptide mediates heterodimerization with PBX
CC       on a regulatory element of the somatostatin promoter. {ECO:0000250}.
CC   -!- DOMAIN: The homeodomain, which contains the nuclear localization
CC       signal, not only mediates DNA-binding, but also acts as a protein-
CC       protein interaction domain for TCF3(E47), NEUROD1 and HMG-I(Y).
CC       {ECO:0000250}.
CC   -!- PTM: Phosphorylated by the SAPK2 pathway at high intracellular glucose
CC       concentration. Phosphorylated by HIPK2 on Ser-268 upon glucose
CC       accumulation. This phosphorylation mediates subnuclear localization
CC       shifting. Phosphorylation by PASK may lead to translocation into the
CC       cytosol (By similarity). {ECO:0000250}.
CC   -!- DISEASE: Pancreatic agenesis 1 (PAGEN1) [MIM:260370]: A disease
CC       characterized by isolated hypoplasia or agenesis of the pancreas,
CC       pancreatic beta-cell failure resulting in neonatal insulin-dependent
CC       diabetes mellitus, and exocrine pancreatic insufficiency.
CC       {ECO:0000269|PubMed:8988180}. Note=The disease is caused by variants
CC       affecting the gene represented in this entry.
CC   -!- DISEASE: Diabetes mellitus, non-insulin-dependent (NIDDM) [MIM:125853]:
CC       A multifactorial disorder of glucose homeostasis caused by a lack of
CC       sensitivity to the body's own insulin. Affected individuals usually
CC       have an obese body habitus and manifestations of a metabolic syndrome
CC       characterized by diabetes, insulin resistance, hypertension and
CC       hypertriglyceridemia. The disease results in long-term complications
CC       that affect the eyes, kidneys, nerves, and blood vessels. Note=Disease
CC       susceptibility is associated with variants affecting the gene
CC       represented in this entry.
CC   -!- DISEASE: Maturity-onset diabetes of the young 4 (MODY4) [MIM:606392]: A
CC       form of diabetes that is characterized by an autosomal dominant mode of
CC       inheritance, onset in childhood or early adulthood (usually before 25
CC       years of age), a primary defect in insulin secretion and frequent
CC       insulin-independence at the beginning of the disease.
CC       {ECO:0000269|PubMed:9326926}. Note=The disease is caused by variants
CC       affecting the gene represented in this entry.
CC   -!- MISCELLANEOUS: According to PubMed:16141209, it may be methylated by
CC       SETD7 in vitro. However, the relevance of methylation is unsure in
CC       vivo. {ECO:0000269|PubMed:16141209}.
CC   -!- SIMILARITY: Belongs to the Antp homeobox family. IPF1/XlHbox-8
CC       subfamily. {ECO:0000305}.
