protein KIAA1881; adipocyte protein S3-12 perilipin-4 (PLIN4, KIAA1881)

Function

• may play a role in triacylglycerol packaging into adipocytes
• may function as a coat protein involved in the biogenesis of lipid droplets (putative)

Structure

belongs to the perilipin family

Compartment

• cell membrane (putative), cytoplasm
• lipid droplet (putative)
• nascent lipid droplet surface-associated; association with lipid droplets is triacylglycerol synthesis-dependent (putative)

Alternative splicing

named isoforms=2

Expression

up-regulated during adipocyte differentiation

More general terms

• perilipin; lipid droplet-associated protein (PLIN)
• membrane protein
