General description

Kifunensine is an alkaloid compound, isolated from the actinomycete Kitasporia kifunensis.

Application

Kifunensine has been used as an inhibitor of mannosidase I in Jurkat T-cells, human embryonic kidney (HEK293T/17) cells and in mouse embryonic fibroblast cells.

Biochem/physiol Actions

Kifunensine is a selective inhibitor of class I glycoprotein-processing α-mannosidases.
Kifunensine suppresses endoplasmic reticulum-associated degradation (ERAD) via the inhibition of endoplasmic reticulum-associated mannosidase activity. It is also a glycosidase inhibitor for Class I CAZy glycosylhydrolase family 47.

Viral infections frequently cause endoplasmic reticulum (ER) stress in host cells leading to stimulation of the ER-associated degradation (ERAD) pathway, which subsequently targets unassembled glycoproteins for ubiquitylation and proteasomal degradation. However, the role of the ERAD pathway in the viral
