Enables mRNA 3'-UTR AU-rich region binding activity. Involved in several processes, including hemopoiesis; negative regulation of cell differentiation; and positive regulation of mRNA catabolic process. Acts upstream of or within hemopoiesis and nuclear-transcribed mRNA catabolic process, deadenylation-dependent decay. Located in cytoplasm and nucleus. Is expressed in several structures, including alimentary system; brain; early conceptus; immune system; and reproductive system. Orthologous to human ZFP36L2 (ZFP36 ring finger protein like 2).
