Expressionⁱ

Tissue specificityⁱ

Expressed primarily in adult heart and skeletal muscle, and detected at lower levels in lung. Isoforms are expressed in a tissue-specific manner. Isoform 1, isoform 3 and isoform 5 are expressed in heart, whereas isoform 2, isoform 4 and isoform 6 are expressed in skeletal muscle.4 Publications

Developmental stageⁱ

Initially expressed in a myocardium-specific manner at 8.5-9 dpc and remains cardiac-restricted until day 12. Strongly expressed throughout heart in all stages examined. At 12.5 dpc expressed at low levels in non-cardiac striated muscles. By day E14.5 expressed at high levels in both cardiac and skeletal muscle, and also strongly expressed in striated muscles of tongue, thoracic and abdominal muscles, leg and diaphragm. The various isoforms are developmentally regulated in both skeletal and cardiac muscle. Isoform 5 and isoform 6, which are barely detectable during embryogenesis are up-regulated postnatally. In heart, isoform 3 is up-regulated developmentally, whereas the predominant isoform 1 is expressed throughout development and into adulthood. In skeletal muscle, the predominant isoform 2 is gradually replaced by isoform 4 postnatally.2 Publications
