- Description
- Predicted to enable DNA-binding transcription factor activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Acts upstream of or within photoreceptor cell development; posterior lateral line neuromast hair cell differentiation; and posterior lateral line neuromast mantle cell differentiation. Predicted to be active in nucleus. Is expressed in several structures, including midbrain neural keel; nervous system; neural plate; pericardial region; and presumptive neural retina. Orthologous to human IRX4 (iroquois homeobox 4).
