Predicted to enable DNA-binding transcription activator activity, RNA polymerase II-specific; RNA polymerase II cis-regulatory region sequence-specific DNA binding activity; and chromatin binding activity. Predicted to be involved in mesoderm formation and regulation of transcription by RNA polymerase II. Predicted to act upstream of or within segment specification and somitogenesis. Predicted to be active in nucleus. Orthologous to human MSGN1 (mesogenin 1). [provided by Alliance of Genome Resources, Apr 2022]
