Tbx5 protein is a transcription factor, which regulates the genes responsible for heart and limb development. Tbx5 has two NLSs and one NES. Both NLSs are required for efficient nuclear localization. During heart and limb development, Tbx5 is dynamically expressed in nuclear and/or cytoplasmic compartments. The interaction and association of Tbx5 with LMP4 can lead to Tbx5 localization along the actin cytoskeleton. Tbx5 can be co-immunoprecipitated with CRM1. The proposed NES region is conserved among all T-box family of proteins. Single mutation of the hydrophobic residues doesn't affect interactions with CRM1, but can prevent cytoplasmic localization in the presence of LMP4. LMP4 is exclusively cytoplasmic.

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.
