External Ids for APOC2 Gene
This gene encodes a lipid-binding protein belonging to the apolipoprotein gene family. The protein is secreted in plasma where it is a component of very low density lipoprotein. This protein activates the enzyme lipoprotein lipase, which hydrolyzes triglycerides and thus provides free fatty acids for cells. Mutations in this gene cause hyperlipoproteinemia type IB, characterized by hypertriglyceridemia, xanthomas, and increased risk of pancreatitis and early atherosclerosis. This gene is present in a cluster with other related apolipoprotein genes on chromosome 19. Naturally occurring read-through transcription exists between this gene and the neighboring upstream apolipoprotein C-IV (APOC4) gene. [provided by RefSeq, Mar 2011]
GeneCards Summary for APOC2 Gene
APOC2 (Apolipoprotein C-II) is a Protein Coding gene. Diseases associated with APOC2 include hyperlipoproteinemia, type ib and familial apolipoprotein c-ii deficiency. Among its related pathways are Signaling by GPCR and Regulation of actin cytoskeleton. GO annotations related to this gene include protein homodimerization activity and phospholipase binding.
UniProtKB/Swiss-Prot for APOC2 Gene
Component of chylomicrons, very low-density lipoproteins (VLDL), low-density lipoproteins (LDL), and high-density lipoproteins (HDL) in plasma. Plays an important role in lipoprotein metabolism as an activator of lipoprotein lipase. Both proapolipoprotein C-II and apolipoprotein C-II can activate lipoprotein lipase. In normolipidemic individuals, it is mainly distributed in the HDL, whereas in hypertriglyceridemic individuals, predominantly found in the VLDL and LDL.
