Beschreibung:
A general caging method for proteins that are regulated by phosphorylation was used to study the in vivo biochemical action of cofilin and the subsequent cellular response. By acute and local activation of a chemically engineered, light-sensitive phosphocofilin mimic, we demonstrate that cofilin polymerizes actin, generates protrusions, and determines the direction of cell migration. We propose a role for cofilin that is distinct from its role as an actin-depolymerizing factor.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ghosh, Mousumi -- Song, Xiaoyan -- Mouneimne, Ghassan -- Sidani, Mazen -- Lawrence, David S -- Condeelis, John S -- GM38511/GM/NIGMS NIH HHS/ -- GM61034/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2004 Apr 30;304(5671):743-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Anatomy and Structural Biology, Albert Einstein College of Medicine, 1300 Morris Park Avenue, Bronx, NY 10461, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15118165" target="_blank"〉PubMed〈/a〉
