Enables mRNA 3'-UTR binding activity and mRNA CDS binding activity. Involved in several processes, including cellular response to amino acid starvation; positive regulation of mRNA binding activity; and regulation of gene expression. Located in cytosol; nucleus; and perinuclear region of cytoplasm. Human ortholog(s) of this gene implicated in hepatocellular carcinoma; lung cancer; and systemic scleroderma. Orthologous to human HNRNPL (heterogeneous nuclear ribonucleoprotein L). [provided by Alliance of Genome Resources, Apr 2022]
