'''Crystal Structure of Murine Coronin-1: monoclinic form'''<br />


==Overview==
==Crystal Structure of Murine Coronin-1: monoclinic form==
Mammalian coronin-1 is preferentially expressed in hematopoietic cells and, plays a poorly understood role in the dynamic reorganization of the actin, cytoskeleton. Sequence analysis of coronin-1 revealed five WD40 repeats, that were predicted to form a beta propeller. They are followed by a 130, residue extension and a 30 residue leucine zipper domain that is, responsible for multimerization of the protein. Here, we present the, crystal structure of murine coronin-1 without the leucine zipper at 1.75 A, resolution. Coronin-1 forms a seven-bladed beta propeller composed of the, five predicted WD40 repeats and two additional blades that lack any, homology to the canonical WD40 motif. The C-terminal extension adopts an, extended conformation, packs tightly against the bottom surface of the, propeller, and is likely to be required for the structural stability of, the propeller. Analysis of charged and conserved surface residues, delineate possible binding sites for F-actin on the beta propeller.

Structural highlights

2b4e is a 1 chain structure with sequence from Mus musculus. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
Method:X-ray diffraction, Resolution 2.3Å
Resources:FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT

Function

COR1A_MOUSE May be a crucial component of the cytoskeleton of highly motile cells, functioning both in the invagination of large pieces of plasma membrane, as well as in forming protrusions of the plasma membrane involved in cell locomotion. In mycobacteria-infected cells, its retention on the phagosomal membrane prevents fusion between phagosomes and lysosomes.[1]

Publication Abstract from PubMed

Mammalian coronin-1 is preferentially expressed in hematopoietic cells and plays a poorly understood role in the dynamic reorganization of the actin cytoskeleton. Sequence analysis of coronin-1 revealed five WD40 repeats that were predicted to form a beta propeller. They are followed by a 130 residue extension and a 30 residue leucine zipper domain that is responsible for multimerization of the protein. Here, we present the crystal structure of murine coronin-1 without the leucine zipper at 1.75 A resolution. Coronin-1 forms a seven-bladed beta propeller composed of the five predicted WD40 repeats and two additional blades that lack any homology to the canonical WD40 motif. The C-terminal extension adopts an extended conformation, packs tightly against the bottom surface of the propeller, and is likely to be required for the structural stability of the propeller. Analysis of charged and conserved surface residues delineate possible binding sites for F-actin on the beta propeller.
