Summary: Predicted to enable DNA-binding transcription activator activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Involved in blood vessel development; hemopoiesis; and positive regulation of angiogenesis. Acts upstream of or within several processes, including G1/S transition of mitotic cell cycle; blood vessel morphogenesis; and embryonic organ development. Located in cytosol and nucleus. Is expressed in several structures, including anterior neural keel; hindbrain neural keel; immature eye; nervous system; and neural rod. Orthologous to human MEIS1 (Meis homeobox 1).

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
