Probably involved in the regulation of pre-mRNA splicing. Interacts with EFTUD2, a component of the spliceosome U5 complex (PubMed:32703943). Interacts with DDX41, a component of the spliceosome C complex (PubMed:32703943). Widely expressed in fetal and adult tissues. Mostly abundant in fetal brain, liver and kidney; in the adult, high levels were also observed in heart, skeletal muscle, spleen, thymus, prostate and small intestine. Expressed in fetal cerebellum and hypothalamus. Low expression is observed in fetal temporal lobe (PubMed:32703943). The disease is caused by variants affecting the gene represented in this entry. Belongs to the FAM50 family.
