CC   -!- FUNCTION: Component of chylomicrons, very low-density lipoproteins
CC       (VLDL), low-density lipoproteins (LDL), and high-density lipoproteins
CC       (HDL) in plasma. Plays an important role in lipoprotein metabolism as
CC       an activator of lipoprotein lipase. Both proapolipoprotein C-II and
CC       apolipoprotein C-II can activate lipoprotein lipase.
CC       {ECO:0000250|UniProtKB:P02655}.
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250|UniProtKB:P02655}.
CC   -!- PTM: Proapolipoprotein C-II is synthesized as a sialic acid containing
CC       glycoprotein which is subsequently desialylated prior to its
CC       proteolytic processing. {ECO:0000250|UniProtKB:P02655}.
CC   -!- PTM: Proapolipoprotein C-II, the major form found in plasma undergoes
CC       proteolytic cleavage of its N-terminal hexapeptide to generate
CC       apolipoprotein C-II, which occurs as the minor form in plasma.
CC       {ECO:0000250|UniProtKB:P02655}.
CC   -!- SIMILARITY: Belongs to the apolipoprotein C2 family. {ECO:0000305}.
