This RNA recognition motif (RRM) is found in human La-related protein 4 (LARP4) and similar proteins predominantly from animals. LARP4 binds to the poly-A tract of mRNA molecules and plays a role in the regulation of mRNA translation and in the regulation of cell morphology and cytoskeletal organisation [2,6].	Domain
