Transcriptional repressor that acts as a negative regulator of chondrocyte maturation. PLays a role in distal gut development; required for proper antral-pyloric morphogenesis and development of antral-type epithelium.

In concert with GSC, defines the structural components of the middle ear; required for tympanic ring and gonium development and in the regulation of the width of the malleus (By similarity). .
