This review details the NF-kappaB1 (p105/p50) transcription factor, exploring its structure, function, and interactions. It highlights NF-kappaB1

Area of Science:

  • Molecular Biology
  • Cellular Signaling
  • Immunology

Background:

  • Nuclear factor kappa B (NF-kappaB) is a key regulator of cellular processes, including inflammation and cell survival.
  • NF-kappaB forms dimers from five subunits: NF-kappaB1 (p105/p50), NF-kappaB2 (p100/p52), RelA (p65), RelB, and c-Rel.
  • The p50:p65 dimer, activated via the classical pathway, typically promotes gene expression and is linked to inflammation and cell survival.

Purpose of the Study:

  • To provide a comprehensive overview of the lesser-characterized NF-kappaB1 subunit (p105 and its processed form, p50).
  • To discuss the interactions of NF-kappaB1 with co-activators, co-repressors, and other signaling networks.
  • To assess the anti-inflammatory actions of NF-kappaB1 signaling and explore therapeutic potential.

Main Methods:

  • Literature review focusing on the structure, synthesis, and function of NF-kappaB1.
  • Analysis of diverse interactions involving NF-kappaB1 within cellular signaling networks.
  • Assessment of existing literature on the anti-inflammatory roles of NF-kappaB1.

Main Results:

  • NF-kappaB1 (p105/p50) plays a significant role in regulating gene expression.
  • NF-kappaB1 interacts with various regulatory proteins and signaling pathways.
  • NF-kappaB1 signaling exhibits anti-inflammatory properties.

Conclusions:

  • NF-kappaB1 (p105/p50) is a crucial transcription factor with diverse regulatory functions.
  • Understanding NF-kappaB1 interactions is vital for comprehending its role in cellular processes.
  • Therapeutic strategies targeting NF-kappaB1 could harness its anti-inflammatory potential.
