Background
X-chromosomal genes mutated in nonspecific mental retardation (MRX) comprise a family of genes, including the gene encoding Cool2/αPix, thought to be involved in mental retardation (3,4).
Cool2/αPix interacts with β-parvin/affixin, a protein involved in integrin signaling (5), and may act downstream of integrin-linked kinase (ILK) to regulate actin reorganization and cell spreading (6).
When Cool2αPix exists as a dimer, it functions as a Rac-specific GEF, whereas the monomeric protein acts as a GEF for both Rac and Cdc42. Regulation of Cool2/αPix dimerization, and therefore its specificity, occurs at least in part through p21 activated kinase (PAK) in response to extracellular signaling (7). Further, binding of Cdc42 enhances the Rac GEF activity of the Cool2/αPix dimer. Activated Rac in turn inhibits Cool2/αPix Rac GEF activity (8).
