Comments
Working together with MSH5, hMSH4 forms a heterodimeric complex and is involved in meiotic chromosomal activity such as homologous recombination and mismatch repair. Co-expression for hMSH4 and hMSH5 improved nuclear localization of both proteins in an LMB-sensitive manner, suggesting interaction between the two proteins contribute to their cellular localization. hMSH4 NES were identified to be between amino acids 421-430 and 797-805. Interaction with VBP1 suggests that hMSH4 might be anchored to the cytoplasm by VBP1 and involved in microtubule assembly to maintain proper chromosomal positioning during meiosis.

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.
