Calretinin: Its Role in Cell Differentiation and as a Potential Tumour Marker

Calretinin is a neuronal calcium-binding protein. It shows marked homology with CBD, and presumably on account of this, calretinin and CBD show mutually exclusive expression in neuronal populations, although in some cell types both may be expressed simultaneously (Rogers and Resibois, 1992). The pattern of their expression and marked similarities between them with respect to calcium-binding properties (Cheung
