CELF2 (CUGBP Elav-Like Family Member 2): CELF2 is a member of the CUG-BP, Elav-like family of RNA-binding proteins, which play essential roles in regulating RNA processing, including alternative splicing, stability, and translation. CELF2 is involved in immune system development and function and has been linked to neurological disorders. Its role in post-transcriptional gene regulation makes it an important factor in cell differentiation and disease development, presenting potential targets for therapeutic intervention.
