Enables several functions, including DNA-binding transcription activator activity, RNA polymerase II-specific; RNA polymerase II cis-regulatory region sequence-specific DNA binding activity; and protein homodimerization activity. Involved in several processes, including endodermal cell differentiation; hematopoietic progenitor cell differentiation; and positive regulation of mesoderm development. Acts upstream of or within animal organ development; digestive tract development; and gastrulation. Located in chromatin and nucleus. Is expressed in several structures, including early embryo; egg cylinder; embryo mesoderm; metanephros; and primitive streak. Orthologous to human MIXL1 (Mix paired-like homeobox).
