Summary
PLIN2 (perilipin 2, HGNC:248) is a protein-coding gene on chromosome 9p22.1, encoding Perilipin-2 (Q99541). Structural component of lipid droplets, which is required for the formation and maintenance of lipid storage droplets.
The protein encoded by this gene belongs to the perilipin family, members of which coat intracellular lipid storage droplets. This protein is associated with the lipid globule surface membrane material, and maybe involved in development and maintenance of adipose tissue. However, it is not restricted to adipocytes as previously thought, but is found in a wide range of cultured cell lines, including fibroblasts, endothelial and epithelial cells, and tissues, such as lactating mammary gland, adrenal cortex, Sertoli and Leydig cells, and hepatocytes in alcoholic liver cirrhosis, suggesting that it may serve as a marker of lipid accumulation in diverse cell types and diseases. Alternatively spliced transcript variants have been found for this gene.

Function. Structural component of lipid droplets, which is required for the formation and maintenance of lipid storage droplets.
Subunit / interactions. Interacts with IRGC.
Subcellular location. Membrane. Lipid droplet.
Tissue specificity. Milk lipid globules.
Post-translational modifications. Acylated; primarily with C14, C16 and C18 fatty acids. Phosphorylation at Tyr-232 by isoform 1 of CHKA (CHKalpha2) promotes dissociation from lipid droplets: dissociation is followed by recruitment of autophagosome machinery to lipid droplets and subsequent lipid droplet lipolysis. Polyubiquitination of Nt-acetylatable A-PLIN2 by MARCHF6 lead to degradation by 26S proteasomes.
Similarity. Belongs to the perilipin family.
