Where this comes from

Abstract

The lysosomal membrane protein TMEM106B functions as a proviral factor in SARS-CoV-2 infection, though it was not known how. In this issue of Cell, Baggen et al. demonstrate that TMEM106B serves as an ACE2-independent receptor for SARS-CoV-2 entry by promoting the fusion of the viral membrane with the lysosomal membrane.
