Gene: VSX1 (visual system homeobox 1) Homo sapiens
Symbol: VSX1
Name: visual system homeobox 1
Description: Predicted to have DNA-binding transcription factor activity, RNA polymerase II-specific; chromatin binding activity; and transcription regulatory region DNA binding activity. Predicted to be involved in neuron development and regulation of transcription, DNA-templated. Predicted to localize to nuclear chromatin. Implicated in corneal dystrophy; keratoconus; and posterior polymorphous corneal dystrophy 1.
Type: protein-coding
RefSeq Status: REVIEWED
