Predicted to enable RNA polymerase binding activity and protein homodimerization activity. Predicted to be involved in several processes, including positive regulation by host of viral genome replication; positive regulation of protein targeting to membrane; and regulation of acid-sensing ion channel activity. Predicted to be located in several cellular components, including membrane raft; mitochondrion; and perinuclear region of cytoplasm. Predicted to be integral component of plasma membrane. Predicted to be active in plasma membrane. Orthologous to human STOM (stomatin). [provided by Alliance of Genome Resources, Apr 2022]
