NF-kappa-B is a pleiotropic transcription factor which is present in almost all cell types and is involved in many biological processed such as inflammation, immunity, differentiation, cell growth, tumorigenesis and apoptosis. NF-kappa-B is a homo- or heterodimeric complex formed by the Rel-like domain-containing proteins RELA/p65, RELB, NFKB1/p105, NFKB1/p50, REL and NFKB2/p52. The dimers bind at kappa-B sites in the DNA of their target genes and the individual dimers have distinct preferences for different kappa-B sites that they can bind with distinguishable affinity and specificity. Different dimer combinations act as transcriptional activators or repressors, respectively. NF-kappa-B is controlled by various mechanisms of post-translational modification and subcellular compartmentalization as well as by interactions with other cofactors or corepressors. NF-kappa-B complexes are held in the cytoplasm in an inactive state complexed with members of the NF-kappa-B inhibitor (I-kappa-B) family. In a conventional activation pathway, I-kappa-B is phosphorylated by I-kappa-B kinases (IKKs) in response to different activators, subsequently degraded thus liberating the active NF-kappa-B complex which translocates to the nucleus. NF-kappa-B heterodimeric RelB-p50 and RelB-p52 complexes are transcriptional activators. RELB neither associates with DNA nor with RELA/p65 or REL. Stimulates promoter activity in the presence of NFKB2/p49. As a member of the NUPR1/RELB/IER3 survival pathway, may provide pancreatic ductal adenocarcinoma with remarkable resistance to cell stress, such as starvation or gemcitabine treatment. Regulates the circadian clock by repressing the transcriptional activator activity of the CLOCK-BMAL1 heterodimer in a CRY1/CRY2 independent manner. Increased repression of the heterodimer is seen in the presence of NFKB2/p52. Is required for both T and B lymphocyte maturation and function (PubMed:26385063).

Rel B also known as RELB proto-oncogene is a member of the NF-κB family of transcription factors. This protein plays a significant role in regulating gene expression. Rel B has a molecular mass of approximately 68 kDa. It expresses in diverse tissues including lymphoid organs and epithelial cells. It generally resides in the cytoplasm and translocates to the nucleus upon activation.
Rel B serves as a critical component of the alternative NF-κB signaling pathway. It often forms a complex with another NF-κB family member called p52. This complex controls the transcription of genes involved in the immune response cell survival and differentiation. Additionally Rel B contributes to the development of secondary lymphoid organs and modulation of immune responses.
Rel B integrates into the non-canonical NF-κB signaling pathway also influencing the canonical pathway to a lesser extent. In the non-canonical pathway Rel B interacts with NIK and p100 to influence immune cell function. This involvement makes Rel B essential in processes like adaptive immunity and inflammatory responses. The protein p52 closely associates with Rel B aiding its activity in these pathways.
Rel B has connections to autoimmune diseases and certain cancers. Abnormal Rel B activity can lead to chronic inflammation and contribute to conditions like rheumatoid arthritis. In cancer its deregulation associates with lymphomas where it may interact with other NF-κB proteins like p50 and RelA affecting cell proliferation and survival. Understanding Rel B in these contexts could provide insights into therapeutic targets.
