Abstract
Cell transformations accompany alterations in cell morphology and microfilament patterns. Calvasculin encodes mRNA termed pEL-98, 18A2, 42A, p9Ka, or mts1, found to be elevated in several metastatic cell lines. We report the elevation of calvasculin expression in SR-3Y1 cells, which show disappearance of ordered microfilaments, compared to that in 3Y1 cells and that the similar distribution of calvasculin to that of actin filaments. Interestingly, calvasculin co-sediments with F-actin and bundles actin filaments in a Ca(2+)-dependent manner. This activity, along with the elevation of calvasculin following transformation, suggests that the disorganization of filaments in SR-3Y1 cell is due to the cross-linking activity of calvasculin.Entities:
