Protein Structure
UniProt Annotation
Function Acts as a transcriptional factor. Specifically binds the insulin enhancer element RIPE3b. Cooperates synergistically with NEUROD1 and PDX1. Phosphorylation by GSK3 increases its transcriptional activity and is required for its oncogenic activity (By similarity). Regulates the insulin gene transcription. Involved either as an oncogene or as a tumor suppressor, depending on the cell context. {ECO:0000250, ECO:0000269PubMed:12917329, ECO:0000269PubMed:14680841, ECO:0000269PubMed:19143053}.
Subcellular Localization Nucleus {ECO:0000255PROSITE- ProRule:PRU00978, ECO:0000269PubMed:12917329}. Note=Detected in nuclei of pancreas islet beta cells.
Disease Associations
Tissue Specificity Selectively expressed in pancreatic beta but not in alpha cells (at protein level). Expressed in eyes and at low levels in thymus. Expressed in brain, lung, spleen and kidney. Expressed in embryo. {ECO:0000269PubMed:12011435, ECO:0000269PubMed:12368292, ECO:0000269PubMed:14680841}.
