WebFeb 8, 2024 · Here, we show that the actin capping protein (CP) is unexpectedly involved in midbody maturation, a poorly understood phase of the cell cycle where cells remodel their intercellular bridges to prepare for separation. The loss of CP results in excessive filamentous actin throughout the cell cycle, but only postfurrowing cytokinesis is inhibited. ... WebCapping protein (CP) regulates actin polymerization by binding the barbed end of an actin filament, which blocks the addition and loss of actin subunits. The new microfilament formation is driven by protein complexes such as Arp2/3 and formins. Arp2/3 proteins are the nuclear ion sites for new microfilaments and formins stabilize transient ... WebComparison of the sequence data with that of other known actin-capping and severing proteins shows no significant homologies, suggesting that Cap Z may be a member of a unique group of capping, nonsevering proteins.

F actin capping protein

WebThe encoded protein reversibly blocks the barbed ends of F-actin filaments in a Ca2+ and phosphoinositide-regulated manner, but does not sever preformed actin filaments. By capping the barbed ends of actin filaments, the encoded protein contributes to the control of actin-based motility in non-muscle cells.
