CUGBP, Elav-like family member 2, also known as Etr-3 is a protein that in humans is encoded by the CELF2 gene.^[1][2][3]

Members of the CELF/BRUNOL protein family are RNA-binding proteins and contain two N-terminal RNA recognition motif (RRM) domains, one C-terminal RRM domain, and a divergent segment of 160-230 aa between the second and third RRM domains. Members of this protein family regulate pre-mRNA alternative splicing and may also be involved in mRNA editing, and translation. Alternative splicing results in multiple transcript variants encoding different isoforms.^[3]

Interactions

CUGBP2 has been shown to interact with A1CF.^[4]
