This COVID-19 event has been created by a combination of computational inference (see https://reactome.org/documentation/inferred-events) from SARS-CoV-1 data and manual curation, as described in the summation for the overall SARS-CoV-2 infection pathway.

Calnexin transiently binds the unfolded spike protein and prevents its aggregation and premature degradation, ensuring its correct folding (Fukushi et al, 2012).
