Expression of α-actinins in zebrafish craniofacial muscles. α-Actinins exhibit diverse expression patterns in craniofacial muscles in zebrafish (5 dpf). A) actn1 expression was detected in intermandibularis anterior (ima), interhyoides (ih), and hyodes inferior (hh). B) actn2 transcripts were strongly expressed in levator arcus palatini (lap) and branchial archs (ba). C) actn3a expression was observed in hyoideus inferior (hi). D) actn3b showed a wide expression pattern in craniofacial muscles including extraocular muscles (eom), levator arcus palatini (lap), adductor operculi (ao), sternohyoides (sh) and branchial arches (ba). E) actn4 expression was restricted to branchial arches (ba).
