Sam68 splicing regulation contributes to motor unit establishment in the postnatal skeletal muscle
RNA-binding proteins orchestrate the composite life of RNA molecules and impact most physiological processes, thus underlying complex phenotypes. The RNA-binding protein Sam68 regulates differentiation processes by modulating splicing, polyadenylation, and stability of select transcripts. Herein, we found that Sam68-/- mice display altered regulation of alternative splicing in the spinal cord of key target genes involved in synaptic functions.
