Nfkb2 Gene Summary [Mouse]

Enables DNA-binding transcription factor activity. Involved in non-canonical NF-kappaB signal transduction. Acts upstream of or within several processes, including follicular dendritic cell differentiation; germinal center formation; and spleen development. Located in nucleus. Is expressed in several structures, including central nervous system; early conceptus; genitourinary system; musculature; and thymus primordium. Used to study common variable immunodeficiency. Human ortholog(s) of this gene implicated in common variable immunodeficiency 10. Orthologous to human NFKB2 (nuclear factor kappa B subunit 2). [provided by Alliance of Genome Resources, Jul 2025]

Protein Domains

A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in mouse Nfkb2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
  • Death domain
  • RNA polymerase II transcription regulatory region sequence-specific binding transcriptional activator activity
  • glycine rich domain
  • transcription regulator
  • Ankyrin repeats (many copies)
  • nucleic acid binding
  • IPT
  • Rel homology dimerization domain
  • alpha helix
  • transcription activation domain
  • Ankyrin repeats (3 copies)
  • protein binding
  • sequence-specific DNA binding
  • Ankyrin repeat
  • phosphorylation site
  • RNA polymerase II transcription factor activity, sequence-specific DNA binding
  • C-terminal death domain
  • double-stranded DNA binding
  • N-terminal sub-domain of the Rel homology domain (RHD)
  • Death Domain Superfamily of protein-protein interaction domains
  • transcription factor activity
  • ankyrin repeats
