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. ... WebFunction. F-actin-capping proteins bind in a Ca 2+ -independent manner to the fast growing ends of actin filaments (barbed end) thereby blocking the exchange of subunits at these ends. Unlike other capping proteins (such as gelsolin and severin), these proteins do not sever actin filaments. May play a role in the formation of epithelial cell ...

Webisolated a Drosophila homologue of the yeast cyclase-associated protein, CAP. Here we show that CAP preferentially accumulates in the oocyte, where it inhibits actin polymerisation. CAP also has a role in oocyte polarity, as cap mutants fail to establish the proper, asymmetric distribution of mRNA determinants within the oocyte. WebThe INM protein emerin, which binds lamins directly, is also a pointed-end F-actin capping protein that enhances actin polymerization in vitro (Holaska et al., 2004). This observation, and associations between emerin, nuclear myosin 1c, and spectrin (discussed below), led to a proposal that the nuclear envelope, ... richard holmwood nssifWebTropomodulin (Tmod) is a unique pointed-end-capping protein first discovered as an actin–tropomyosin-binding protein (Figure 4 ). The name tropomodulin was given because it binds actin filaments tightly in the presence of tropomyosin. Human skeletal muscle Tmod has a mass of about 40 kDa. Four isoforms of Tmod have been identified, … red line around artboard illustrator
