“…Although the lens epithelium contains actin bundles arranged in polygonal arrays (Lonchmpt et al, 1976 ;Traas and Ramaekers, 1986 ;Rafferty and Scholz, 1989), we have not observed in this study a similar polygonal array of actin bundles in cortical fiber cells. It is possible that actin bundles in epithelial cells may undergo certain configurational changes during differentiation and elongation into fiber cells.…”

“…Whether the lens filaments are related to polypeptide 3, or to polypeptide 5 with molecular weight similar to muscle actin, requires further study. This is pertinent in view of the demonstration of actin filaments in lens epithelial cells [Rafferty and Esson, 1974;Longchampt et a!., 1976;Mousa and Trevithick, 1977].…”

Regional Differences in the Polypeptide Composition of Chick Lens Intracellular Matrix

Analysis of the chick lens intracellular matrix by SDS polyacrylamide gel electrophoresis revealed that the cortical urea-soluble protein is characterized by a high content of non-crystallin polypeptides, especially those of molecular weights of 85,000, 49,000 and 41,000 daltons. The nuclear urea-soluble fraction (USF) consists mainly of δ- and α-crystallins, and of a polypeptide of 41,000 daltons molecular weight. The 11- and 17-day-old embryonic USF is enriched in δ-crystallin and the polypeptide of molecular weight 49,000 daltons.

“…These Factins are shown to be continuously associated with the cell membranes in the nuclear ®ber cells without being proteolysed . However, actin bundles are arranged in polygonal arrays extending throughout the major part of the cytoplasm in the lens epithelium and epithelial cultures (Lonchampt et al, 1976;Rafferty and Scholz, 1989). In contrast, actin bundles are arranged into long chains with periodic short intervals, and distributed along the cell corners and parallel to the long axis of hexagonal ®ber cells (Lo et al, 1997).…”
