Summary: This gene is a member of the Antp homeobox family and encodes a nuclear protein with a homeobox DNA-binding domain. It is included in a cluster of homeobox B genes located on chromosome 17. The encoded protein functions as a sequence-specific transcription factor that is involved in development. Intracellular or ectopic expression of this protein expands hematopoietic stem and progenitor cells in vivo and in vitro, making it a potential candidate for therapeutic stem cell expansion.

Study revealed that HOXB4 was highly expressed in ovarian cancer cells. HOXB4 silencing enhanced the cytotoxic effect of Taxol and DDP by downregulating ABC transporters via inhibition of the PI3K/Akt signaling pathway. These results for the first time elucidated the critical roles and molecular basis of HOXB4 underlying drug resistance in ovarian cancer cells.

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.
