Correction: EGR1 functions as a potent repressor of MEF2 transcriptional activity.

The images for Figs ​Figs1,1, ​,3,3, ​,4,4, and ​and55 are previous versions of the figures. Please see the correct figures here. Fig 1 EGR1 is a potent repressor of MEF2 transcriptional activity. Fig 3 EGR1 and MEF2A interact in vitro. Fig 4 Costamere gene expression is sensitive to EGR1 levels in NRVMs. Fig 5 Costamere gene expression is upregulated in EGR1-depleted NRVMs.
