| Subcellular_localization | Generally, DRE-1::GFP was localized to both the nucleus and cytoplasm, and it was broadly expressed, including in phenotypically affected tissues. | ||
| Type | Reporter_gene | For dre-1::gfp, a 4 kb promoter was amplified with primers 5' -GGTACCCGAGGGGACATCGAGATAG-3' and 5' -GGTACCTTCCTGGCCAACCAGAGAC-3' and was cloned into Fire vector L3781 (BA 279). The dre-1 ORF and the dre-1 3' UTR region were amplified with primers 5' -GCTAGCATGTCGTCCTCTTCGTCAC-3' and 5' -ACTAGTTACTTACTCCACTCCACACAG-3' and were cloned into BA279 (BA280). Lines containing this construct included dhEx346 and dhIs442. To obtain the full-length promoter construct, authors substituted the promoter from BA279 with a 12.3 kb promoter by using primers 5' -GCGGCCGCGTTGCACACAAAACATTATTATTTTCTTTCTCTT-3' and 5' -TACGTATCTCGTCCCTGAGATCTCTCATTT-3' (BA508). Resulting lines containing this array included dhEx443 and dhEx452. --precise ends. | |
| Pattern | First detected by midembryogenesis, expression was most prominent in epidermal and intestinal cells. By the 1.5-fold stage of embryogenesis, expression was additionally detected in neurons and other cells. During larval and adult stages, DRE-1::GFP was most visible in epidermal seam cells and hypodermis. Expression was high in larvae and low in adults. In addition, DRE-1 was strongly expressed in the P epidermal blast cells and descendents that give rise to the vulva. Weak expression was seen in the somatic gonad, including the gonadoblasts, the anchor cell, dtcs, and occasionally adult spermatheca and uterus. Notably, with another construct (dhEx346, 4 kb promoter, 4 kb coding region), dtc expression was stronger and commenced by mid-L3. In the musculature, DRE-1 was seen in the pharynx, anal depressor, sex muscles, and body wall muscles. Finally, DRE-1 was detected in neurons of the head, tail, ventral cord, and periphery. | ||
