※ IKK family introduction

    IKKs family contains four members, IKKα, IKKβ and two IKK-related kinases, IKKε and NAK, which have been identified with sequence similarity to IKKα and IKKβ. Sequence analysis of IKKs shows that IKKα and IKKβ contain a kinase catalytic domain in its N-terminal and followed by three function motif, known as LZ(leucine zipper), HLH(helix-loop-helix) and NBD(NEMO-binding domain). Activation of IKKs is associated with NF-κB signaling pathway which is triggered by different receptors, including members of TNFR family, members of the IL-1R and Toll-Like receptor (TLR) family and antigen receptors. All IKKs are implicated in the regulation of NF-κB activity and IKKs act as key regulator in various physiological and pathophysiological functions including host defense response, inflammation, cell survival, cancer, metabolic regulation, and neuroadaptation (1).
