BACKGROUND Calnexin is a new type of molecular chaperone that interacts with many nascent membrane and soluble proteins of the secretory pathway. It is a calcium-binding, endoplasmic reticulum (ER)-associated protein that interacts transiently with newly synthesized N-linked glycoproteins, facilitating protein folding and assembly. Calnexin is unrelated to molecular chaperones of the Hsp60, Hsp70 and Hsp90 families, and is further distinguished from them in that it is an integral membrane protein.1 It may also play a central role in the quality control of protein folding by retaining incorrectly folded protein subunits within the ER for degradation.2 Alternatively spliced transcript variants encoding this protein have been described.
