Description

General description

CUGBP Elav-like family member 4 (UniProt: Q9BZC1; also known as CELF-4, Bruno-like protein 4, CUG-BP- and ETR-3-like factor 4, RNA-binding protein BRUNOL-4) is encoded by the CELF4 (also known as BRUNOL4) gene (Gene ID: 56853) in human. CELF-4 is a RNA-binding protein that is implicated in the regulation of pre-mRNA alternative splicing. It is ubiquitous in its distribution, but is strongly expressed in the cerebellum, hippocampus, amygdala, temporal and frontal cortex, and frontal lobes. It mediates exon inclusion and/or exclusion in pre-mRNA that are subject to tissue-specific and developmentally regulated alternative splicing. It is shown to specifically activate exon 5 inclusion of cardiac isoforms of TNNT2 during heart remodeling at the juvenile to adult transition. CELF-4 is reported to promote exclusion of both the smooth muscle and non-muscle exons in actinin pre-mRNAs. It binds to muscle-specific splicing enhancer (MSE) intronic sites flanking the alternative exon 5 of TNNT2 pre-mRNA. The N-terminal region (aa 1-298) is considered to be sufficient for its RNA-binding and MSE-dependent splicing activity. CELF-4 contains contain two N-terminal RNA recognition motif (RRM) domains (aa 54-135 and 152-232) and one C-terminal RRM domain (aa 404-479). Five isoforms of CELF-4 have been described that are produced by alternative splicing.

Specificity
