TMEM106B (Transmembrane Protein 106B) is a conserved type II transmembrane protein predominantly localized in late endosomes and lysosomes. First identified in 2004. its gene maps to human chromosome 7p21 and encodes a 274-amino-acid protein containing a cleavable signal peptide, transmembrane domain, and conserved coiled-coil regions. While its precise physiological function remains incompletely understood, TMEM106B appears to regulate lysosomal trafficking, acidification, and organelle size through interactions with microtubule-associated proteins and membrane fusion machinery.
This protein gained significant attention in neurodegeneration research after genome-wide studies linked TMEM106B polymorphisms to frontotemporal lobar degeneration (FTLD) risk, particularly in progranulin (GRN)-associated cases. The major risk allele (rs3173615) influences TMEM106B expression levels and correlates with enhanced age-related lysosomal dysfunction. Paradoxically, TMEM106B overexpression exacerbates lysosomal abnormalities in cellular models, while its depletion ameliorates neuronal deficits in GRN-deficient systems, suggesting a complex dose-dependent relationship with lysosomal homeostasis.
Recombinant TMEM106B proteins, typically produced in mammalian or insect cell systems with epitope tags, enable structural-functional studies of its cytoplasmic domain's liquid-liquid phase separation properties and interactions with partners like AP2M1 and MAP6. These tools have revealed TMEM106B's role in maintaining lysosomal membrane dynamics and autophagic flux. Current research employs recombinant proteins to map disease-associated mutations, develop targeted antibodies, and screen small molecule modulators. However, challenges persist in resolving full-length membrane protein structures and reproducing native post-translational modifications. TMEM106B recombinant tools continue to drive critical insights into lysosome biology and proteinopathy mechanisms across neurodegenerative diseases.
