Fragile X mental retardation protein: A paradigm for translational control by RNA-binding proteins.

abstract：:Although believed to be widely distributed among the animal kingdom, transforming growth factor-beta (TGF-beta) superfamily members have mainly been characterized in vertebrate and in invertebrate model organisms such as Drosophila and C. elegans. To characterize such new factors in invertebrates, a PCR screen was per...
