Tissue specificity：Mainly expressed in the skeletal muscle (isoform 1 and isoform 2 but not isoform 3), and weakly in the heart. Also found in the retina and the distal tube of kidney. Expressed in skeletal muscle, nasal epithelium, cochlea, parathyroid and salivary gland (PubMed:11313460). Expressed in muscle satellite cells of normal and regenerating muscles (PubMed:20696153). {ECO:0000269|PubMed:11313460, ECO:0000269|PubMed:20696153}.
Induction：
Developmental stage：At 8.5 dpc expressed at the surface ectoderm outside the neural folds, somites, presomitic mesoderm. At 9.5 dpc expressed at the nasal and otic placodes, cranial ganglia, branchial arches, somites (dermamyotomes and sclerotomes). At 10.5-11.5 dpc expressed at the nasal pits, otic vesicles, cranial ganglia, dorsal root ganglia, branchial arches, somites, myotomes, limb mesenchyme, notochord, mesonephros. At 12.5-13.5 dpc expressed in skeletal muscles, mesenchyme in limbs and digits, nasal epithelium, inner ear (PubMed:11313460). Weakly expressed in the nephrogenic cord on 9.5 dpc and in the metanephric mesenchyme on 10.5 dpc (PubMed:17300925). At 11.5 dpc expressed in the epithelium of the lateral lingual swellings, and in the tongue epithelium, mesenchyme, and muscles at 12.5 dpc. In the fungiform papillae, expressed in the epithelium at 14-16.5 dpc. In the circumvallate and foliate papillae, expression is observed in the trench wall of these papillae at 15.5 dpc-P0 (PubMed:21978088). At 11.5 dpc mainly found in limbs, and somites, where is expressed in the dorsal root ganglion, myotomes, and ventral and dorsal dermomyotomal lips (PubMed:15788460). Expressed in a wide domain of the ectoderm in the presumptive olfactory region and in the thickened olfactory placode. Expressed in the peripheral precursors of the pit. At 12.5 dpc-14.5 dpc, expression become progressively restricted to the apical and basal progenitors.Also expressed strongly in the preplacodal region at 8.0 dpc and in the presumptive olfactory ectoderm at 9.0 dpc (PubMed:19027001). At 10.5 dpc expressed in the progenitors of the dermomyotome and in the myocytes (PubMed:19962975). {ECO:0000269|PubMed:11313460, ECO:0000269|PubMed:15788460, ECO:0000269|PubMed:17300925, ECO:0000269|PubMed:19027001, ECO:0000269|PubMed:19962975, ECO:0000269|PubMed:21978088}.
