RBFOX1 (RNA Binding Fox-1 Homolog 1): RBFOX1 is an RNA binding protein that plays a key role in regulating alternative splicing. It influences 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 important for neuronal development, synaptic function, and muscle cell differentiation. Proper RBFOX1 activity is essential for central nervous system development, and its dysregulation has been linked to neurological disorders such as epilepsy and autism spectrum disorders.
