Comments
Mut-S homologous protein 5 (MSH5), in a heterodimer with MSH4, is essential for the processing and/or stabilization of meiotic DNA recombination intermediates. While hMSH4 exhibits a limited expression profile, hMSH5 is involved in various cellular processes and interacts with other proteins. Although the putative carboxy-terminus NES of amino acids 802-811 was not itself tested for sufficiency, a mutant deletion of the four critical residues (Mutant 7) was inserted into Rev(1.4)-GFP control and exhibited limited export acitivity. Mutant 7 was also unable to interact with hMSH4, whereas mutagenesis of hMSH5 NLS did not affect interaction between hMSH4 and hMSH5. This further verified that the NES is located in the hMSH4-binding domain towards the carboxy-terminus of hMSH5. hMSH5 is found to be less stable and to have a shorter half-life in the nucleus due to degradation by nuclear proteosome 26S.

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.
