Is an ortholog of human MYT1 (myelin transcription factor 1)\; MYT1L (myelin transcription factor 1 like)\; and ST18 (ST18 C2H2C-type zinc finger transcription factor). Is predicted to have DNA-binding transcription activator activity, RNA polymerase II-specific and RNA polymerase II regulatory region sequence-specific DNA binding activity. Is involved in nematode larval development. Is expressed in head neurons and the g1. Human ortholog(s) of this gene are implicated in autosomal dominant non-syndromic intellectual disability 39.
