Interleukin-1 receptor-associated kinase 1-binding protein 1 (IRAK1BP1)

Target
IRAK1BP1
Molecular classification
Signal transduction adaptor protein, Other (not a receptor, enzyme, transporter, channel, or transcription factor; acts as a scaffold/adaptor in immune signaling)
01

Overview

Interleukin-1 receptor-associated kinase 1-binding protein 1 (IRAK1BP1) is a cytoplasmic and nuclear protein that functions as a signaling adaptor in the IRAK1-dependent TNFRSF1A pathway, leading to activation of NF-κB and regulation of cell survival[1][4][7]. IRAK1BP1 modulates the balance between pro- and anti-inflammatory responses by promoting the nuclear translocation of inhibitory p50/p50 NF-κB homodimers over p65/p50 heterodimers, facilitating increased IL-10 (anti-inflammatory cytokine) production and suppressing proinflammatory cytokines such as IL-6[2]. This protein thus serves as an innate immune modulator, supporting the resolution phase of inflammation and contributing to endotoxin (LPS) tolerance in macrophages[2]. While not a classic drug target (enzyme, receptor, channel), it is an emerging candidate for modulation in diseases of excessive or insufficient inflammation, though no specific therapeutics are approved for direct IRAK1BP1 targeting.

Biological functions

Signal transduction (main effector is the NF-κB pathway)Immune response (modulates innate immune signaling through inflammation resolution)Cell survival (required for cell survival under cytokine stimulation)
03

Disease associations

Inflammation (modulator of pro- and anti-inflammatory responses)Infection (shapes response to immune stimuli such as Toll-like receptor agonists)Other (linked to syndromic disease such as Chung-Jansen Syndrome and Schizophrenia, but these associations are not well defined mechanistically)

Safety considerations

No direct therapeutic interventions; but as a central modulator of inflammatory signaling, non-specific inhibition or activation could present risks of immune dysfunction or excessive inflammation[2]
