Enables several functions, including 14-3-3 protein binding activity; mRNA 3'-UTR AU-rich region binding activity; and protein-RNA sequence-specific adaptor activity. Involved in several processes, including cellular response to cytokine stimulus; cellular response to epidermal growth factor stimulus; and regulation of gene expression. Acts upstream of or within mRNA catabolic process. Located in cytoplasmic ribonucleoprotein granule; cytosol; and nucleus. Part of ribonucleoprotein complex. Biomarker of breast cancer.
