Actin is the most abundant protein in most eukaryotic cells. It is highly conserved and participates in more protein-protein… Expand Spatial and functional organization of cells in tissues is determined by cell-cell adhesion, thought to be initiated through… Expand The actin cytoskeleton is a complex structure that performs a wide range of cellular functions. In 2001, significant advances… Expand The dynamics and polarity of actin filaments are controlled by a conformational change coupled to the hydrolysis of adenosine 5… Expand Cell division, cell motility and the formation and maintenance of specialized structures in differentiated cells depend directly… Expand Rac is a Rho‐family small GTPase that induces the formation of membrane ruffles. However, it is poorly understood how Rac‐induced… Expand Two related cellular proteins, p80 and p85 (cortactin), become phosphorylated on tyrosine in pp60src-transformed cells and in… Expand Actin-binding protein (ABP-280, nonmuscle filamin) is a ubiquitous dimeric actin cross-linking phosphoprotein of peripheral… Expand C YTOCHALASINS and phalloidins are two groups of small, naturally occurring organic molecules that bind to actin and alter its… Expand The peripheral cytoplasm of macrophages is involved in the control of locomotion, secretion and endocytosis, events common to… Expand
