Enables long noncoding RNA binding activity and mRNA 3'-UTR AU-rich region binding activity. Involved in posttranscriptional regulation of gene expression; protein import into nucleus; and regulation of stem cell population maintenance. Acts upstream of or within positive regulation of translation. Located in several cellular components, including cytoplasmic stress granule; glutamatergic synapse; and postsynapse. Part of ribonucleoprotein complex. Is expressed in several structures, including alimentary system; central nervous system; early conceptus; genitourinary system; and sensory organ. Orthologous to human ELAVL1 (ELAV like RNA binding protein 1). [provided by Alliance of Genome Resources, Apr 2022]
