GLIS3

Monday 7 April 2008

Definition! GLIS3 (GLI-similar 3) is a member of the GLI-similar zinc finger protein family encoding for a nuclear protein with 5 C2H2-type zinc finger domains. The protein is expressed early in embryogenesis and plays a critical role as both a repressor and activator of transcription. Human GLIS3 mutations are extremely rare.

Functions

GLIS3 is expressed in the pancreas from early developmental stages, with greater expression in beta cells than in other pancreatic tissues.

These results demonstrate a major role for GLIS3 in the development of pancreatic beta cells and the thyroid, eye, liver and kidney.
