Hox B4 (Homeobox Protein B4, HOXB4, HOX-B4, Homeobox 2F, Hox 2F, HOX 2, Hox 2.6)

Homeobox protein HOXB4 belongs to the Antp homeobox family which functions as sequence-specific transcription factor which is part of a developmental regulatory system that provides cells with specific positional identities on the anterior-posterior axis. Enforced expression of HOXB4 in human neonatal keratinocytes results in increased cellular proliferation and colony formation as well as decreased expression of the alpha-2-integrin and CD44 cell surface adhesion molecules. In fetal human skin HOXB4 protein expression was both nuclear and cytoplasmic within epidermal basal cells and in hair follicle inner and outer root sheath cells, whereas strong nuclear signals were observed in the bulge region. In adult skin, HOXB4 protein expression was both nuclear and cytoplasmic, but was predominantly localized to the intermediate and differentiated cell layers. In contrast to the striking gradient patterns of HOX gene and protein expression previously described in developing spinal cord and limb, HOXB4 protein was uniformly detected in all regions of the fetal and adult skin. It is also reported that enforced expression of the HoxB4 gene promotes expansion of hematopoietic stem cells (HSCs) and enhances hematopoietic development of both murine and human embryonic stem (ES) cells.\n\nApplications:\nSuitable for use in Immunohistochemistry.
