Is affected by 20-hydroxyecdysone based on proteomic studies. Is predicted to encode a protein with the following domains: Armadillo-type fold; Armadillo-like helical; HEAT repeat; HEAT repeats; and Vacuolar 14 Fab1-binding region. Is an ortholog of C. elegans paa-1. In C. elegans, paa-1 is involved in embryo development.
