Overlapping homologous superfamilies

Family relationships


NS1 is a homodimeric RNA-binding protein found in influenza virus that is required for viral replication. NS1 binds polyA tails of mRNA keeping them in the nucleus. NS1 inhibits pre-mRNA splicing by tightly binding to a specific stem-bulge of U6 snRNA [PMID: 9360601].
