Is affected by 20-hydroxyecdysone based on proteomic studies. Is predicted to encode a protein with the following domains: Clathrin adaptor complex small chain; Longin-like domain superfamily; Adaptor protein complex, sigma subunit; and AP complex, mu/sigma subunit. Is an ortholog of C. elegans aps-1
. In C. elegans, aps-1
Is involved in apical protein localization.
