Target Information

Calnexin (also known as IP90, p88, p90) is an approximately 90 kDa integral membrane protein of the endoplasmic reticulum (ER).
ER-resident proteins act as molecular chaperones, aiding proper folding and assembly of polypeptides.
Calnexin associates with MHC class I heavy chains, partial T cell receptor complexes, and B cell membrane immunoglobulin, but not with completed receptor complexes.
It functions as a chaperone retaining incompletely or improperly folded proteins in the ER.

Soluble ER proteins such as GRP78, GRP94, and protein disulfide isomerase have a KDEL sequence at the carboxy-terminus for ER retention.
Integral membrane ER proteins like calnexin lack KDEL but contain positively charged cytosolic residues ensuring ER retention.

Calnexin structure:

• ER luminal domain: 461 amino acids
• Transmembrane segment: 22 amino acids
• Cytoplasmic tail: 89 amino acids
