Adaptor Protein Nf Kb

All tlr signaling pathways culminate in activation of the transcription factor nuclear factor kappab nf κb which controls the expression of an array of inflammatory.

Adaptor protein nf kb. A family of toll like receptors tlrs acts as primary sensors that detect a wide variety of microbial components and elicit innate immune responses. Nf κb nuclear factor kappa light chain enhancer of activated b cells is a protein complex that controls transcription of dna cytokine production and cell survival nf κb is found in almost all animal cell types and is involved in cellular responses to stimuli such as stress cytokines free radicals heavy metals ultraviolet irradiation oxidized ldl and bacterial or viral antigens. Knipe proceedings of the national academy of sciences aug 2008 105 32 11335 11339. Nf κb describes various dimeric complexes of members of the rel protein family which comprises rel c rel rel a p65 relb nf κb1 p50 and its precursor p105 and nf κb2 p52 and its precursor p100 ghosh et al 1998 each possesses an 300 residue n terminal rel homology domain responsible for dimerisation nuclear translocation and dna binding.

P65 relb and c rel also contain. As only p65 rel relb and c rel have carboxy terminal transactivation domains tad the nf kb family of proteins can. Recently role of adaptors have emerged in the regulation of nf κb.
