Final answer:
The adaptor protein that activates the NF-κB pathway is MyD88.
Step-by-step explanation:
The adaptor protein that activates the NF-κB pathway is MyD88.
The NF-κB pathway is a signaling pathway that controls the expression of genes involved in immune response, cell survival, and inflammation. MyD88 is an adaptor protein that plays a key role in the activation of the NF-κB pathway.
Upon stimulation by specific ligands, such as Toll-like receptors (TLRs) or interleukin-1 receptors (IL-1Rs), MyD88 recruits and activates a protein complex that leads to the activation of NF-κB, resulting in the expression of target genes.
