CELF2 (also known as CUG-BP2 or CUGBP Elav-Like Family Member 2) is an RNA-binding protein involved in post-transcriptional regulation of gene expression. It plays critical roles in alternative splicing, mRNA translation, and RNA stability. [@ladd2007]
Overview
Structure
CELF2 contains three RNA recognition motifs (RRMs) in the central and C-terminal regions:
RRM1 and RRM2: High-affinity RNA binding
RRM3: Protein-protein interactions
N-terminal Region: Low-complexity, involved in splicing regulation
The protein forms dimers and can interact with other RNA-binding proteins.
Normal Function
RNA Processing
Regulates alternative splicing by binding to GU-rich elements (GREs)
Modulates inclusion/exclusion of exons in target pre-mRNAs
Key targets include [tau](/proteins/tau) exon 10, [NMDA](/entities/nmda-receptor) receptor subunits
Translation Regulation
Controls translation initiation through interaction with eIF2α
