Comments
ERG is a helix-turn-helix DNA binding domain transcription factors with anti-inflammatory functions in endothelial and hematopoietic cells, but have also been found pathologically expressed in disease. 30 possible isoforms have been proposed - Hoesel et al. examined 5 main isoforms including, ERG1(NM_182918), ERG1b(M21535.1), ERG3 (NM_001136154.1), ERG4 (NM_001136155) and ERG8 (this entry). All of the isoforms are found to shuttle when expressed in cells, with ERG8 predominantly localized to the cytosol and the rest in the nucleus. The authors identified putative NLS in the DNA-binding domain which is absent in ERG8, a putative NES which is found in all isoforms (192-203 in ERG1, 100-111 in ERG1b and ERG4, 199-210 in ERG3 and ERG8; does not match NES consensus) and a putative NES specific for ERG8 (298-310; match NES consensus but with excess hydrophobic residues). Leucine mutations to the second NES caused more significant nuclear accumulation and additional mutation to the first NES had no further effect. However authors proposed weak activity of NES1 in the other isoforms as leucine mutations caused slight nuclear accumulation. No LMB sensitivity was tested.

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.
