RBFOX1 (RNA Binding Fox-1 Homolog 1): RBFOX1 is an RNA-binding protein that plays a crucial role in regulating alternative splicing. It affects the diversity and function of mRNA transcripts in the nervous system and skeletal muscle. By targeting a wide range of pre-mRNAs, RBFOX1 modulates splicing patterns to control gene expression vital for neuronal development, synaptic function, and muscle cell differentiation. Proper RBFOX1 activity is essential for the development of the central nervous system, and its dysregulation has been associated with neurological disorders such as epilepsy and autism spectrum disorders.
