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. Acts upstream of or within cellular response to leukemia inhibitory factor and mitotic spindle assembly. Located in nucleus. Part of Myb complex. Is expressed in several structures, including brain; early conceptus; genitourinary system; hemolymphoid system; and skin. Used to study acute myeloid leukemia and myelodysplastic syndrome. Orthologous to human MYBL2 (MYB proto-oncogene like 2). [provided by Alliance of Genome Resources, Dec 2024]

Protein-protein interaction studies showed that YAP binds directly to B-MYB, a subunit of MMB, in a manner dependent on the YAP WW domains and a PPXY motif in B-MYB. Disruption of the interaction by overexpression of the YAP binding domain of B-MYB strongly inhibits the proliferation of cardiomyocytes.

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.
