Radixin is a cytoskeletal protein that may be important in linking actin to the plasma membrane. It is highly similar;in sequence to both ezrin and moesin. The radixin gene has been localized by fluorescence in situ hybridization to;11q23. A truncated version representing a pseudogene (RDXP2) was assigned to Xp21.3. Another pseudogene that seemed to;lack introns (RDXP1) was mapped to 11p by Southern and PCR analyses. Multiple alternatively spliced transcript;variants encoding different isoforms have been found for this gene.
