Proper heart development and synchronous cardiomyocyte contraction rely on tissue integrity. Here the authors show that the ubiquitin-proteasome system and the E3 ubiquitin ligase ASB2 in particular are crucial for cardiomyocyte maturation and tissue integrity through the degradation of the TCF3 transcription factor.
