Probably acts downstream of the Wnt signaling pathway. Expressed in the seam cells, and in the hyp7 syncytial hypodermis in the mid-L4 larval stage (PubMed:24569038). Not expressed in the cells of the developing vulva (PubMed:24569038). RNAi-mediated knockdown causes dumpy body shape (PubMed:24569038). Defects in cuticle integrity (PubMed:24569038).
