“…Position-based analysis of Matrin3 disorder reveals that the region between RRM2 and ZnF2 have the highest tendency for disorder, while the region spanning the RRMs has the lowest. Considering the recent computational successes in describing the structural features and dynamics of disordered proteins ( Cino et al, 2011 ; Krzeminski et al, 2012 ; Do et al, 2014 ; Ramis et al, 2019 ; Pietrek et al, 2020 ; Wilson et al, 2021a ; Chang et al, 2021 ), molecular simulation of specific protein segments could help to more accurately characterize Matrin3, FUS, and TDP-43, by producing a structural ensemble rather than a single frame. Computational methods have also been extended to study protein aggregation propensities ( Morriss-Andrews and Shea, 2015 ), liquid-liquid phase-separation ( Paloni et al, 2020 ; Benayad et al, 2021 ), IDP-protein interactions ( Cino et al, 2013 ; Do et al, 2016 ; Karttunen et al, 2018 ), and the effects of mutation ( Vacic et al, 2012 ; Wilson et al, 2021b ) and post-translational modification ( Jin and Graeter, 2021 ; Sieradzan et al, 2021 ) on protein structure, all potential avenues for investigation of a disordered ALS protein like Matrin3.…”
