Abstract

In this report, we analyzed the apm-2 and aps-2 genes, which encode the nematode homologues of the medium chain and the small chain of the plasma membrane-associated clathrin-associated protein complex AP-2, respectively. We determined the genomic structure of the two genes. We show that apm-2 and aps-2 genes are expressed in most, if not all, cells during embryogenesis, and that the two genes are expressed primarily in neurons and some hypodermal cells following hatching through adulthood. RNA interference experiments showed that the reduction of either apm-2 or aps-2 gene function causes embryonic lethality, larval lethality at various stages of development, and other morphological defects in the larval stages. These results indicate that apm-2 and aps-2 gene functions are required during both embryogenesis and larval stages, and that their functions may be required in proper neuronal functions.
