Homeobox protein Hox-B9 is a protein that in humans is encoded by the HOXB9 gene.^[5][6][7]

Function

This gene is a member of the Abd-B homeobox family and encodes a protein with a homeobox DNA-binding domain. It is included in a cluster of homeobox B genes located on chromosome 17. The encoded nuclear protein functions as a sequence-specific transcription factor that is involved in cell proliferation and differentiation. Increased expression of this gene is associated with some cases of leukemia, prostate cancer and lung cancer.^[7]

Interactions

HOXB9 has been shown to interact with BTG2^[8] and BTG1.^[8]
