Probable membrane-bound O-acyltransferase (By similarity). Together with GUP1, has an influence on the chemical composition of the yeast extracellular matrix (yECM) in yeast multicellular aggregates, such as biofilms and colonies (PubMed:25589358). Expressed constitutively. Belongs to the membrane-bound acyltransferase family. Was originaly thought to be involved in active uptake of glycerol driven by electrogenic proton symport (PubMed:10931309), but has later been shown to be an acyltransferase and that effects on glycerol transport may be indirect (PubMed:15381122).
