therefore , the presence of filamin and actin but not myosin in these specialized regions on the cell surface , together with the recent demonstration [ wang , k. & singer , s. j . ( 1977 ) proc . natl . acad . sci . usa 74 , 2021-2025 ) ] that pure filamin interacts with individual f-actin filaments in solution to form fiber bundles and sheet-like structures , suggest that in vivo filamin-actin interactions play an important role in the control of actin filament structure , in cell motility , and in the stabilization of cell-cell contacts .
