"We confirmed that Myc-TRA-2c5 induced the expression of a vitellogenin reporter gene (vit-2::GFP) (Yi and Zarkower 1999) in transgenic XO animals (see below; Fig. 6)."
FOS-1b, JUN-1a-c and JUN-1d are Coexpressed in the spermatheca, and different AP-1 dimers formed between these isoforms have distinct effects on the activation of a reporter gene.
