| Summary: | Understanding of pancreatic islet biology has greatly increased over the past few decades based in part on an increased understanding of the transcription factors that guide this process. One such transcription factor that has been increasingly tied to both β-cell development and the development of diabetes in humans is <i>GLIS3</i>. Genetic deletion of <i>GLIS3</i> in mice and humans induces neonatal diabetes, while single nucleotide polymorphisms (SNPs) in <i>GLIS3</i> have been associated with both Type 1 and Type 2 diabetes. As a significant progress has been made in understanding some of <i>GLIS3</i>’s roles in pancreas development and diabetes, we sought to compare current knowledge on <i>GLIS3</i> within the pancreas to that of other islet enriched transcription factors. While <i>GLIS3</i> appears to regulate similar genes and pathways to other transcription factors, its unique roles in β-cell development and maturation make it a key target for future studies and therapy.
