Gsx (gene family)
The Gsx gene family are a group of genes found in many, but not all, animals. Gsx genes contain a homeobox DNA sequence and code for proteins that act as transcription factors. The human genome has two Gsx genes, called GSX1 and GSX2, while the fruitfly Drosophila has a single Gsx gene called ind. Vertebrate Gsx genes are implicated in neural patterning. In many animals, Gsx genes can be part of a ParaHox gene cluster.
