Hi Judith, I have a question about an insertion line that you generated. It has been referred to in the literature as 17-en-52, an insertion of a P element that contains 'lacZ' into exon 1 of en. The paper I am curating is: \*x FBrf0084183 == Mellerick and Nirenberg, 1995, Dev. Biol. 171(2): 306--316 Have you published this insertion anywhere? I couldn't find it in your PNAS, Genes Dev or either of the Genetics papers. If not, please could you tell me which P element inserted into en to cause this allele? That way I can get the details more correct than vague... with best wishes, Rachel Ref: rd2353.h Rachel: 17en52 was one of the insertions of Pen1(rosy) generated in our PNAS paper. We list 7 insertions into 48A in Table 1, but don't name the lines. Best wishes, Judy
