Predicted to enable mRNA 3'-UTR binding activity. Involved in determination of adult lifespan. Located in nucleus. Expressed in body wall musculature; cloacal sphincter muscle; copulatory spicule; non-striated muscle; and somatic gonad. Human ortholog(s) of this gene implicated in developmental and epileptic encephalopathy 97. Is an ortholog of human CELF1 (CUGBP Elav-like family member 1).
Members of the CELF/BRUNOL protein family 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. Multiple alternatively spliced transcript variants encoding different isoforms have been identified in this gene. [provided by RefSeq, Feb 2010]
