Members of this family adopt a structure consisting of an alpha+beta sandwich with an antiparallel beta-sheet, arranged in a 2(beta-alpha-beta) motif. They are mainly found in mRNA export factors, and mediate the sequence nonspecific nuclear export of cellular mRNAs as well as the sequence-specific export of retroviral mRNAs bearing the constitutive transport element [1].

The vertebrate Tap protein is a member of the NXF family of shuttling transport receptors for nuclear export of mRNA. Tap has a modular structure, and its most C-terminal domain is important for binding to FG repeat-containing nuclear pore proteins (FG-nucleoporins) and is sufficient to mediate nuclear shuttling [1]. The structure of the C-terminal domain is composed of four helices [1]. The structure is related to the UBA domain.	Domain
