Disease Context (from Entrez Summary) IL1B is implicated in:
  • Inflammatory response - key mediator
  • Osteoarthritis pathogenesis
  • COVID-19 - elevated in severe cases (BAL fluid)
  • SARS-CoV-2 lung damage (cytokine-mediated)
  • Cell proliferation, differentiation, apoptosis
  • COX-2 induction in CNS (inflammatory pain)

I’ve compiled a comprehensive cross-database identifier and functional mapping reference for human IL1B (Interleukin-1 beta). The document includes: Key Highlights:

  • 64 PDB structures (highest resolution: 1.16 Å)
  • 8,488 protein interactions in STRING
  • 1,816 AlphaMissense predictions for missense variants
  • 573 SpliceAI splice predictions
  • 99 GO annotations covering molecular function, cellular component, and biological processes
  • 228 tissues with detected expression (ubiquitous pattern, highest in immune cells)
  • 18 DrugBank entries and Pomalidomide as an approved Phase 4 drug
  • VIP status in PharmGKB with 24 drug associations IL1B is a master regulator of inflammation, processed by Caspase-1 from its proform, and signals through IL1R1/IL1RAP. It has strong GWAS associations with dysmenorrheic pain severity (p=2×10⁻¹⁶) and allergic diseases.
