BACKGROUND: Members of the @entity68394 ( @entity68394 ) family function as cell adhesion molecules and cell surface receptors. The @entity3392 genome contains six different @entity68394 genes, and @entity68395 and @entity68396 were shown to be essential for myoblast fusion during skeletal muscle development. However, little is known about @entity68394 -b2 expression and function. RESULTS: We isolated the cDNA of @entity3392 @entity68397 . @entity68394 -b2 is expressed specifically in extraocular muscles (EOMs), jaw muscles, and pectoral fins in @entity3392 larvae, but not in trunk muscles. The identified @entity68397 expression pattern is supported by the analysis of a @entity3392 Gal4-enhancer trap line, in which the coding sequence of the transcriptional activator KalTA4 together with a Gal4-dependent UAS-mCherry expression cassette was inserted into the @entity68397 locus. Intercrosses with an UAS:EGFP strain proves the possibility for targeting transgene expression to EOMs, jaw muscles and fins. Finally, we characterized the concerted contraction pattern of EOMs in larvae performing an optokinetic response. CONCLUSIONS: The expression pattern of @entity68394 -b2 suggests that it may contribute different properties to EOMs, jaw muscles, and pectoral fins. The @entity68394 -b2:KalTA4-UAS-mCherry transgenic strain serves a dual role as both a reporter for these muscles and as a valuable genetic tool for targeting transgene expression to EOMs. Developmental Dynamics, 2015.    2015 Wiley Periodicals, Inc.
