General description

Rel B is part of the NFκB complex and forms heterodimeric complexes with p50 (NFKB1) and p52 (NFKB2). The homodimeric complexes of Rel B alone do not show DNA-binding activity. IHC analysis has shown that Rel B expression correlated with dendritic cell activation. NFκB-inducing kinase NIK is required for osteoclastogenesis in response to pathologic stimuli and overexpression of Rel B rescues differentiation of mouse NIK -/- osteoclast precursors. Rel B is required for RANKL-induced osteoclastogenesis in vitro and for TNF -induced bone resorption in vivo. This indicates that the alternative NFκB pathway, via Rel B, plays an essential and unique role in RANKL signaling toward osteoclast development.

NF-kappaB inducing kinase (NIK) is required for osteoclastogenesis in response to pathologic stimuli, and its loss leads to functional blockade of both alternative and classical NF-kappaB caused by cytoplasmic retention by p100. We now show that deletion of p100 restores

RelB belongs to the family of Rel-related proteins, dimers of which determine NF-kappa B activity. The murine RelB protein has been reported to be a dimerizing partner in kappa B-binding complexes which are capable of transactivation. On the other hand
