    text
  • is always present in the mitochondrial fraction
  • NFKB family members NFKB2 and RELB translocate to the nucleus in response to CO2
  • basic FUNCTION
  • can repress proinflammatory gene expression, and its expression in sepsis patient blood leukocytes may play a role in the endotoxin-tolerant phenotype
  • functionally associated with the aryl hydrocarbon receptor (AHR) and mediates transcription of chemokines such as IL8
  • NF-kappaB subunit downstream of MAP3K14 responsible for osteoclast differentiation
  • playing a role in the crosstalk between non-hematopoietic stromal cells and leukemic cells
  • contributes to tumorigenicity of prostate cancer
  • responsible for the lipopolysaccharide-mediated attachment and may play an important role in the progression of some cancers
  • inhibits cell proliferation and tumor growth in a TP53-dependent manner
  • function for RELB as an important regulator of the mammalian circadian system in fibroblasts
  • RELB controls dendritic cell (DC) maturation
  • negatively regulates osteoblast differentiation and bone formation
  • is a novel regulator of human pluripotent stem cells (hPSCs) proliferation, suggesting a new function for RELB, in addition to its widely accepted role as a transcription factor, the post-transcriptional modulation of IGF2 and cell-cycle gene expression
  • role of RELB on lymphocyte development , and in the absence of RELB, B cells development is arrested, resulting in poor production of immunoglobulins and specific antibodies
  • critical role for the combined activity of the RELB and NFKB2 subunits in B cell homeostasis that cannot be compensated for by the canonical NFKB pathway under physiological conditions
  • functioned as an oncogene in prostate cancer
  • CELLULAR PROCESS
    PHYSIOLOGICAL PROCESS
    PATHWAY
    metabolism
    signaling
  • RELB/NFKB2 signaling positively and intrinsically regulates hematopoietic stem/progenitor cell (HSPC) self-renewal and maintains stromal/osteoblastic niches
  • a component
  • RELB/NFKB1 regulates CCL19 production, but fails to promote dendritic cells maturation
  • INTERACTION
    DNA
    RNA
    small molecule
    protein
  • ARNT is a TNFRSF8-interacting protein that modulated the activity of the RELB subunit of the transcription factor nuclear factor kappaB (NF-kappaB)
  • interacting with DPF2 (functions as an efficient adaptor protein between the SWI/SNF complex and RELB and plays important roles in noncanonical NF-kappaB transcriptional activation and its associated oncogenic activity)
  • GSK3B is a crucial regulator of RELB degradation, stressing the relevant linkage between the NFKB system and GSK3B
  • CHUK and IKBKB are RELB interacting partners whose activation by TNF promotes RELB phosphorylation at serine 472
  • SIRT1-RELB induction of mitochondrial biogenesis included increases in mitochondrial mass, mitochondrial-to-nuclear DNA ratios, and both nuclear and mitochondrial encoded proteins
  • TNFSF13B signals coordinate both RELB and REL activities to ensure survival during peripheral B-cell maturation
  • RELB is necessary for the effective production of downstream TNFRSF11A(+) mTEC (medullary Thymic epithelial cells) progenitors
  • NKRF is a novel RELB-response gene, and Neutrophil elastase (NE) is a stimulator of the non-canonical RELB/NFKB1 pathway in airway smooth muscle cells
