    Notes: Summary In the differentiated pigmented epithelial cells of the retina (RPE) of chick embryos cytoskeletal proteins are found in polygonal rings located in the cell cortex. Within the cortical rings of the RPE cells vinculin and spectrin occupy a characteristic position closest to the plasma membrane; actin is found farther away, while tropomyosin and myosin are located farthest from the plasma membrane. The differences in the distribution of these proteins might reflect the functional specialization of different parts of the cortical ring required to develop and transmit tension from individual cells throughout the entire epithelial sheet.

    Widespread tissue distribution of rabbit calreticulin, a non-muscle functional analogue of calsequestrin (1992)

    Notes: Summary Calreticulin was identified in a variety of rabbit tissues by Western blot analysis. Indirect immunofluorescence studies on cultured cells or frozen sections from the corresponding tissues revealed that the protein was distributed to the endoplasmic reticulum or sarcoplasmic reticulum. Calreticulin was found to be an abundant calcium-binding protein in non-muscle and smooth muscle cells and a constitutent calcium-binding protein in cardiac and skeletal muscle. From the immunoblot data, calreticulin may exist as an isoform in rabbit neural retina. The present study establishes the ubiquity of calreticulin in intracellular calcium binding.
