Publication: Abu-Daya A, Sater AK, Wells DE, Mohun TJ, Zimmerman LB. Absence of heartbeat in the Xenopus tropicalis mutation muzak is caused by a nonsense mutation in cardiac myosin myh6. Dev Biol. 2009;336(1):20-9.

The muz allele encodes a truncated myh6 protein lacking the myosin coiled-coil tail, muz mutants show significantly diminished expression of myh6 mRNA in heart and jaw muscle. Image published in Abu-Daya et al. (2010)
