ABIN1 (TNFAIP3 Interacting Protein 1), also known as TNIP1, is a cytosolic protein that plays a critical role in regulating NF-κB signaling and cell survival. The protein contains multiple domains that mediate protein-protein interactions and ubiquitin binding, making it a key regulator of inflammatory responses. ABIN1 serves as an adaptor protein that connects TNFAIP3 (A20) with downstream signaling components, forming a critical brake on NF-κB activation.
ABIN1 contains several functional domains with distinct roles:
ABIN1 functions as a critical negative regulator of NF-κB signaling through multiple mechanisms:
ABIN1/TNIP1 has emerged as a significant GWAS risk locus for late-onset Alzheimer's disease:
