Transcription factor (By similarity). Probably acts downstream of the Wnt signaling pathway (PubMed:24569038). Expressed during the larval L1 to adult stages, with little or no change in transcript levels (PubMed:24569038). Expressed in several head neurons during L4 larval stage in hermaphrodites (PubMed:24569038). RNAi-mediated knockdown causes hypodermal or cuticular rupture, typically in the anterior body region (PubMed:24569038). Abnormal gap between the outer layer of hypodermis and muscle and the internal organs, perhaps due to defects in cuticle integrity (PubMed:24569038). Belongs to the Sp1 C2H2-type zinc-finger protein family.
