Additional Information
Statement
Reference

Expression is observed in the precursor cells of the longitudinal visceral muscles.

(Georgias et al., 1997)

Reporter gene expression is observed in embryos in the head region during early and late stages and in several mesoderm-related expression domains in the trunk.

(Hacker et al., 1995)
