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].

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.
