RNPC3 and neurodegenerative disease: An additional point of convergence between RNP granules and neurodegenerative disease was revealed by the appreciation that disease-associated RNA can undergo LLPS even in the absence of protein (Jain and Vale 2017) and that these RNA–RNA interactions contribute to RNP granule assembly (Van Treeck and Parker 2018; Van Treeck et al. 2018).
