It is also unclear how actin and myosin are targeted to the cell cortex. Active RhoA initiates polymerization of equatorial actin by relieving self-inhibition of formins, ... WebbCell division cycle 25A (Cdc25A) is a dual-specificity phosphatase that is overexpressed in several cancer cells and promotes tumorigenesis. In normal cells, Cdc25A expression is regulated tightly, but the changes in expression patterns in cancer cells that lead to tumorigenesis are unknown. In this study, we showed that ubiquitin-specific protease 29 …
