Nfkb2 Protein is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
Overview
NFKB2 (Nuclear Factor Kappa B Subunit 2), also known as p100 or p52, is a member of the [NF-κB](/entities/nf-kb) transcription factor family. NFKB2 is synthesized as a full-length p100 precursor that is processed to the active p52 subunit. It plays crucial roles in immune responses, inflammation, cell survival, and neuronal function. Dysregulation of NFKB2 is implicated in neurodegenerative diseases, cancer, and autoimmune disorders [@bours1994][@senftleben2001].
Protein Information
Structure
NFKB2 has unique features:
N-terminal RHD — Rel homology domain for DNA binding
C-terminal ankyrin repeats — Inhibitory domain (in p100)
Processing site — Proteolytic cleavage to generate p52
Transactivation domain — Present in p52
Processing is constitutive or inducible via the NF-κB inducing kinase (NIK) [@xiao2001].
Normal Function
NF-κB Signaling
NFKB2 functions in:
Alternative pathway — Non-canonical NF-κB signaling
Lymphoid development — B cell and lymphoid organ formation
The study of Nfkb2 Protein has evolved significantly over the past decades. Research in this area has revealed important insights into the underlying mechanisms of neurodegeneration and continues to drive therapeutic development.
Historical context and key discoveries in this field have shaped our current understanding and will continue to guide future research directions.
