Crystal structure of the GTP-binding protein-like domain of AGAP1.

ABSTRACT: AGAP1 is often considered to regulate membrane trafficking, protein transport and actin cytoskeleton dynamics. Recent studies have shown that aberrant expression of AGAP1 is associated with many diseases, including neurodevelopmental disorders and acute lymphoblastic leukemia. It has been proposed that the GTP-binding protein-like domain (GLD) is involved in the binding of cofactors and thus regulates the catalytic activity of AGAP1. To obtain a better understanding of the pathogenic mechanism underpinning AGAP1-related diseases, it is essential to obtain structural information. Here, the GLD (residues 70-235) of AGAP1 was overexpressed in Escherichia coli BL21 (DE3) cells. Affinity and gel-filtration chromatography were used to obtain AGAP1_GLD with high purity for crystallizati
