Summary: Predicted to enable DNA-binding transcription factor activity, RNA polymerase II-specific and RNA polymerase II transcription regulatory region sequence-specific DNA binding activity. Predicted to be involved in regulation of transcription by RNA polymerase II. Is expressed in several structures, including amnioserosa anlage; anlage in statu nascendi; anterior-posterior subdivision of organism; ganglia; and neuroblasts. Human ortholog(s) of this gene implicated in X-linked lissencephaly 2; X-linked recessive disease (multiple); corpus callosum agenesis-abnormal genitalia syndrome; and syndromic X-linked intellectual disability Hedera type. Orthologous to human ARX (aristaless related homeobox). [provided by Alliance of Genome Resources, Nov 2024]
