title: Calreticulin: from Ca2+ binding to control of gene expression.
abstract: Calreticulin is a highly conserved Ca(2+)-binding/storage protein of the endoplasmic reticulum (ER). Recently, it has been shown to play a role in the control of gene expression by interacting with the DNA-binding domain of various steroid receptors. How does this ER protein gain access to the nuclear steroid receptors? We propose that calreticulin undergoes unique intracellular trafficking that allows it to colocalize with and bind to steroid receptors.
