NFkB p65

The IKK complex, or inhibitor of NFkB kinase, is composed of IKK alpha and IKK beta.  These kinases are at the core of the NFkB signaling cascade.  The NFkB family is made up of transcription factors that are kept inactive in the cytoplasm through inhibitory IkB proteins.

NF-kappa-B is a ubiquitous transcription factor involved in several biological processes such as inflammation, immunity, differentiation, cell growth, tumor genesis and apoptosis. Unlike the majority of transcription factors that reside in the nucleus, NFkB is predominantly bound to IkBs protein inhibitors and is located in the cytoplasm. There are two major signaling pathways involved in the activation of NFkB, canonical and non-canonical. [1] In the canonical NF-kB pathway, NF-kB activation is dependent on the inducible degradation of IkBs, particularly IkBa.

Nuclear Factor kappa B (NFkB) binds to the kappa-beta site of the immunoglobulin kappa light chain gene enhancer. Thus NFkB has become one of the widely studied transcription factors in innate and adaptive immune responses.

Apoptosis is one of the main types of programmed cell death which involves a cascade of biochemical events leading to specific cell morphology characteristics and ultimately death of cells.
