Enables mRNA 3'-UTR binding activity. Acts upstream of or within RNA splicing. Located in cytoplasm and nucleus. Is expressed in several structures, including alimentary system; central nervous system; eye; genitourinary system; and lung. Used to study amyotrophic lateral sclerosis type 6. Human ortholog(s) of this gene implicated in amyotrophic lateral sclerosis; amyotrophic lateral sclerosis type 6; essential tremor 4; liposarcoma; and neurodegenerative disease. Orthologous to human FUS (FUS RNA binding protein). [provided by Alliance of Genome Resources, Apr 2022]
