Calretinin, a calcium-binding protein with a molecular weight of 29 kD, is a member of the large family of EF-hand proteins that also includes S-100 protein. This antibody is useful for differentiating mesotheliomas from adenocarcinomas. Positive tissue: Human normal pleura lining/ malignant mesothelioma.
Expected Staining Pattern: Cytoplasmic and nuclear
Calretinin is encoded by the CALB2 gene located on chromosome 16. It is a troponin C superfamily protein having six EF-hand structural motifs. The EF motif allows the protein to bind calcium, and function in calcium signaling, calcium buffering, and modulating neuronal excitability. Calretinin is expressed in the mesothelium, mast cells, some neural cells, hair follicles, and fat cells.
