Predicted to enable RNA binding activity; SUMO binding activity; and hyaluronic acid binding activity. Predicted to be involved in several processes, including PML body organization; cellular response to mechanical stimulus; and positive regulation of gene expression. Predicted to act upstream of or within hyaluronan metabolic process. Located in cytoplasm. Is expressed in central nervous system; ovary; retina; and white fat. Orthologous to human HABP4 (hyaluronan binding protein 4). [provided by Alliance of Genome Resources, Apr 2022]
