Comments
Pat1 proteins play important roles in translational regulation, mRNA deadenylation, and mRNA decay. There are two Pat1 proteins in vertebrates: Pat1a and Pat1b, while in yeast and invertebrates, there is only one. Marnef et al. showed that Pat1b is a CRM1-dependent nucleocytoplasmic shuttling protein. It is located to P-bodies in cytoplasm and accumulates in splicing speckles and in nuclear foci. The export signal is from aa 86-95. NLS remains unidentified. Pat1a is not CRM1-dependent.

User Input
Accurate identification of NESs is difficult because many sequences in the genome match the NES consensus. Therefore, some published NESs may be mistakenly identified. Please help us improve the accuracy of NESdb by providing either a positive or negative flag for the NES in this entry. Supporting comments are required to process the flag.
