Cytohesins
WebJul 1, 2010 · The cytohesins are also known to interact with several other signaling scaffolds, including GRASP/tamalin, CASP/Cybr/CYTIP, and GRSP1, and binding of the cytohesins to all of these scaffolds, including the CNKs, requires the cytohesin CC domain. Thus, it appears that a critical function of the CC domain is to mediate binding of the … WebNov 26, 2013 · Cytohesins, a family of Arf-activating proteins, have been extensively implicated in the regulation of Arfs during migration and cell shape change. Membrane association of both the Arf and its activating protein is a prerequisite for Arf activation. Therefore regulating the extent of cytohesin membrane association is a mechanism for …

One of them is the cytohesin family represented by three members in D. discoideum, SecG, Sec7 and a further protein distinguished by several transmembrane domains. Cytohesins are …
WebCytohesins have been suggested as a new effective target for reducing invasion, metastasis, and Cetuximab or Panitumumab-resistant cells in colorectal cancer patients. The possibility that cytohesins can be new targets for drug-resistant or advance-stage cancer patients have been explored. Accordingly, we examined WebCytohesins are upregulated in a variety of cancers, and the authors show that inhibition of cytohesin activity impairs the growth of EGFR-dependent lung carcinomas in mice. The data demonstrate a novel role for cytohesins in the allosteric activation of an important family of receptor tyrosine kinases, and identify them as potential targets for ...
