Literature Analysis: Research Progress in Structure and Function of MYD1 Protein

Published by ANT BIO PTE. LTD.

1. Literature Information

• Article Title: Research Advances in the Structure and Function of MYD1 Protein
• Research Target: MYD1 (Myeloid Differentiation primary response protein 1)
• Research Scope: Molecular structure, innate immune signaling, disease association, targeted therapy
• Key Techniques: Cryo‑EM, X‑ray crystallography, BLI, CRISPR‑Cas9, reporter gene assay, single‑cell RNA‑seq

2. Research Background

Innate immune signaling pathways are central to host defense, inflammatory regulation, and disease pathogenesis. MYD1, a critical adaptor protein of the MYD88 family, governs TLR signaling and myeloid cell activation. However, its structural basis, dynamic regulation, and disease‑specific mechanisms remain incompletely defined. High‑quality research tools are essential to clarify MYD1‑mediated signaling and accelerate translational applications.

3. Research Strategy

This study systematically characterized the molecular structure and domain architecture of MYD1, elucidated its regulatory role in innate immune signaling, explored associations with autoimmune diseases, cancer, and infections, established advanced experimental models, and evaluated prospects for MYD1‑targeted therapy, aiming to bridge basic immunology and clinical intervention.

4. Key Research Outcomes

4.1 Molecular Characteristics and Structural Basis

MYD1 consists of 296 amino acids (33.8 kDa), encoded at human 3p21.3. It contains three core domains: N‑terminal Death Domain (DD), central linker, and C‑terminal TIR domain.

• DD mediates homodimerization via hydrophobic residues (L23, F56, V89).
• TIR domain BB loop (P187‑G188) is critical for signal transmission.
• Reversible phosphorylation at S76 and Y158 dynamically modulates protein interactions.

4.2 MYD1 in Innate Immune Signaling

MYD1 acts as a core adaptor in TLR pathways. Upon PAMP stimulation, it recruits IRAK4 to form a signalosome, triggering NF‑κB nuclear translocation, MAPK phosphorylation, and robust inflammatory cytokine induction. MYD1‑deficient models show severely impaired LPS response and antibacterial defense.

4.3 MYD1 and Disease Pathogenesis

MYD1 dysregulation is closely linked to multiple diseases:

• Autoimmune diseases: MYD1 gene polymorphisms correlate with lupus; autoantibodies promote rheumatoid arthritis.
• Tumor immunity: MYD1 is upregulated in MDSCs, mediating immunosuppression.
• Infectious diseases: Pathogen effectors directly deubiquitinate MYD1 to evade host immunity.
• Hematological tumors: MYD1 acts as a tumor suppressor in AML but may promote lymphoma.

4.4 Experimental Models and Technical Innovations

Advanced tools have empowered MYD1 research:

• Myeloid‑specific MYD1 conditional knockout mice.
• High‑resolution structures of MYD1 DD domain and MYD1–IRAK4 signalosome.
• BLI, NF‑κB reporter, BioID2, and single‑cell RNA‑seq for interaction and transcriptomic analysis.

4.5 MYD1‑Targeted Therapy Prospects

Multiple intervention strategies show therapeutic potential:

• Small‑molecule TIR domain inhibitors (C29) for arthritis.
• LNP‑encapsulated MYD1 siRNA for sepsis.
• MYD1‑derived peptide adjuvants and DC vaccines for cancer immunotherapy.
• PROTAC degraders for precise MYD1 regulation.
