Enables palmitoyl-(protein) hydrolase activity. Involved in several processes, including negative regulation of protein localization to microtubule; positive regulation of protein localization to endosome; and protein depalmitoylation. Located in plasma membrane; postsynaptic density; and recycling endosome membrane. Orthologous to human ABHD17B (abhydrolase domain containing 17B, depalmitoylase).
