'''ACANTHAMOEBA CASTELLANII PROFILIN II'''
===ACANTHAMOEBA CASTELLANII PROFILIN II===




==Overview==
<!--
We determined the structures of Acanthamoeba profilin I and profilin II by x-ray crystallography at resolutions of 2.0 and 2.8 A, respectively. The polypeptide folds and the actin-binding surfaces of the amoeba profilins are very similar to those of bovine and human profilins. The electrostatic potential surfaces of the two Acanthamoeba isoforms differ. Two areas of high positive potential on the surface of profilin II are candidate binding sites for phosphatidylinositol phosphates. The proximity of these sites to the actin binding site provides an explanation for the competition between actin and lipids for binding profilin.
The line below this paragraph, {{ABSTRACT_PUBMED_8078936}}, adds the Publication Abstract to the page
(as it appears on PubMed at http://www.pubmed.gov), where 8078936 is the PubMed ID number.
