    Summary
    Enables fatty acid synthase activity and serine hydrolase activity. Involved in several processes, including cellular response to sucrose stimulus; cellular triglyceride homeostasis; and triglyceride biosynthetic process. Acts upstream of with a positive effect on regulation of lipid storage. Is expressed in adult fat body; adult head; adult heart; and embryonic/larval fat body. Orthologous to human FASN (fatty acid synthase). [provided by Alliance of Genome Resources, Apr 2022]
