Predicted to be involved in mRNA splicing, via spliceosome. Predicted to be located in cytosol; nuclear membrane; and nucleoplasm. Predicted to be part of U2-type precatalytic spliceosome and U4/U6 x U5 tri-snRNP complex. Human ortholog(s) of this gene implicated in Burn-McKeown syndrome. Orthologous to human TXNL4A (thioredoxin like 4A). [provided by Alliance of Genome Resources, Apr 2022]
