First, we built an
aex-2 transcriptional reporter Paex-2::mNeonGreen, and found that
aex-2 was mainly expressed in the nervous system with some in the posterior gut, which is consistent with the previous report (Wang et al, 2013).Second, we co-expressed Paex-2::mNeonGreen with the AIY-specific marker Pttx-3::mCherry, and found that the expression of those two reporters overlapped, indicating that
aex-2 is expressed in AIY interneurons.
