Members of this family are involved in mediating U snRNA export from the nucleus. They adopt a highly helical structure, wherein the polypeptide chain forms a right-handed solenoid. At the tertiary level, the domain is composed of a superhelical arrangement of successive antiparallel pairs of helices .
This entry represents an MIF4G-like domain. MIF4G domains share a common structure but can differ in sequence. This entry is designated
