what are actin filaments edit actin filaments f actin are linear polymers of globular actin g actin subunits and occur as microfilaments in the cytoskeleton and as thin filaments which are part of the contractile apparatus in muscle and nonmuscle cells see contractile bundles
CELLULAR ADHESION MOLECULES 91 Thus, modulation of syndecan expression may be required for the maintenance of some tumors.67 In humans, Ridley et al68 have examined syndecan expression, structure, and function on myeloma cells.
Most bind extracellular matrix molecules and provide cell matrix interactions Some subfamilies bind cell surface adhesion molecules and are involved in cell-cell interactions.
