质量标准:【产品介绍】Homeobox transcription factors (Hox) are
highly conserved developmental proteins that are involved
in embryonic and early hematopoietic
development. Specifically, Homeobox B4 (HoxB4) is
a transcription factor that is involved in the
developmental regulation of specific positional
identities on the anterior-posterior axis of cells. Like
all members of the HOX family, HoxB4 is abundantly
expressed in primitive hematopoietic stem cells (HSC),
but then it declines with lineage-specific
terminal differentiation (1). In HSC's, stem
cell self-renewal activity is regulated by USF1/2 binding
to HoxB4, where binding possibly favors stem
cell self-renewal instead of cell differentiation. Jun-B
and Fra-1 have been linked to key mediators during
cell proliferation and differentiation induced by
HoxB4, which leads to an increase in expression of Cyclin
D1 and G1 shortening (2).
