Comments
Tmod is the capping protein for the pointed end of actin filaments. E-Tmod is one of four isoforms of Tmod. Wild-type Tmod is located in the cytoplasm in Tmod-rich cardiac myocytes. Moderate nuclear accumulation was noticed after LMB treatment. Mutations L134D/L135E or L135/V showed nuclear localization. It is not clear why L135 to another hydrophobic aa can disrupt nuclear export. Amino acids 340-343 were proposed to be NLS as indicated by mutation studies. Ho

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.
