WebA protein phosphatase is a phosphatase enzyme that removes a phosphate group from the phosphorylated amino acid residue of its substrate protein. Protein phosphorylation is one of the most common forms of reversible protein posttranslational modification ( PTM ), with up to 30% of all proteins being phosphorylated at any given time. WebSpecial Issue Information. Signal transduction is the process of cell communication with the external environment. Aberrant signal transduction is a prerequisite for cancer progression and metastasis. The crosstalk of cancer cells with stromal cells, including fibroblasts and immune cells, further augments cancer progression and metastasis.
WebMay 18, 2016 · Eukaryotic receptor signal transduction often relies on regulators that ensure that signal transduction is shut off in the absence of a stimulus [11–13]. An earlier study showed that a small GTPase ROP11 can directly bind to ABI1 and release ABI1 from phosphatase activity inhibition by the monomeric ABA receptor RCAR1/PYL9 . Here, we …
