Expression in the embryos starts at around 4 cell stage. Not expressed in the germline. Expression was seen in neurons and body-wall muscle. Strong beta-gal staining and green fluorescence were observed in the central nervous system. Dorsal and ventral nerve cord also gave a strong signal. Staining was also found in the intestinal lining and the body wall muscle. Transgenic chromosomal arrays are not usually expressed in the germline. However, they are observed to express in early embryos. micro-array data shows that
atx-2 present in the germline of L3 and L4 larvae.
