title: STATus report on tetramers.
abstract: STAT proteins bind DNA as dimers to regulate gene expression. Cooperative recruitment of pairs of dimers (tetramers) to adjacent DNA sites has also been documented. In this issue, Lin et al. (2012) examined tetramer function in vivo and showed that STAT5 tetramers function primarily as transcriptional activators.
