ACANTHAMOEBA CASTELLANII PROFILIN IB

Structural highlights

1acf is a 1 chain structure with sequence from Acaca. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
Resources:	FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT

Function

[PRO1A_ACACA] Binds to actin and affects the structure of the cytoskeleton. At high concentrations, profilin prevents the polymerization of actin, whereas it enhances it at low concentrations. By binding to PIP2, it inhibits the formation of IP3 and DG.

Evolutionary Conservation

Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf.

Publication Abstract from PubMed

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.

X-ray structures of isoforms of the actin-binding protein profilin that differ in their affinity for phosphatidylinositol phosphates.,Fedorov AA, Magnus KA, Graupe MH, Lattman EE, Pollard TD, Almo SC Proc Natl Acad Sci U S A. 1994 Aug 30;91(18):8636-40. PMID:8078936^[1]
