CC -!- FUNCTION: Calcium-binding protein that interacts with newly CC synthesized glycoproteins in the endoplasmic reticulum. It may act CC in assisting protein assembly and/or in the retention within the CC ER of unassembled protein subunits. It seems to play a major role CC in the quality control apparatus of the ER by the retention of CC incorrectly folded proteins. CC -!- SUBCELLULAR LOCATION: Endoplasmic reticulum; endoplasmic reticulum CC membrane; single-pass type I membrane protein. CC -!- SIMILARITY: Belongs to the calreticulin family.
