Figure Legend Snippet: Figure 1. Overview of native TMEM106B (A) Schematic view of TMEM106B with its N-ter- minal domain (NTD), transmembrane domain (TM), and C-terminal domain (CTD). (B) A predicted structure of TMEM106B from ROBETTA (Kim et al., 2004) colored with the same scheme as (A), indicating sites at which the C-terminal domain may get cleaved. (C) Aggregation propensity mapped onto a pre- dicted structure of TMEM106B(120–254) from AlphaFold (Jumper et al., 2021) (positive values in blue indicate soluble regions and negative values in red correspond to aggregation-prone regions).

Figure Legend Snippet: Figure 6. Structure-based model of a possible interrelationship between TMEM106B, aggregated filaments, and lysosomes in neurodegenerative diseases Under physiological conditions, TMEM106B spans the lysosomal/endosomal membrane. Upon cleavage of the C-terminal fragment, TMEM106B(120–254) fibrils may form. It is currently unknown whether TMEM106B(120–254) fibrillizes in the lumen or whether lysosomal leakage occurs and TMEM106B(120–254) fragments aggregate into fibrils in the cytosol. Based on our set of TMEM106B fibril structures, we speculate that the aggregation of TMEM106B(120–254) into fibrils leads to lysosomal dysfunction, which promotes the accumulation of aberrantly aggregated amyloid fibrils such as those formed by TDP-43 (PDB:7PY2, green sticks), tau (PDB:7P65, blue sticks), or a-synuclein.
