Enables identical protein binding activity and lipase binding activity. Involved in several processes, including negative regulation of peroxisome proliferator activated receptor signaling pathway; positive regulation of sequestering of triglyceride; and regulation of lipid metabolic process. Located in cytosol and lipid droplet. Orthologous to human PLIN5 (perilipin 5). [provided by Alliance of Genome Resources, Apr 2022]
