DE RecName: Full=Apolipoprotein C-III; DE Short=Apo-CIII; DE Short=ApoC-III; DE AltName: Full=Apolipoprotein C3; DE Flags: Precursor; GN Name=APOC3; OS Cavia porcellus (Guinea pig). OC Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; OC Mammalia; Eutheria; Euarchontoglires; Glires; Rodentia; OC Hystricognathi; Caviidae; Cavia. OX NCBI_TaxID=10141; RN [1] RP NUCLEOTIDE SEQUENCE [MRNA]. RC TISSUE=Liver; RX PubMed=10584299; DOI=10.1016/S0305-0491(99)00097-8; RA Yin Y., Olivecrona G.; RT "Apolipoprotein CIII from guinea pig (Cavia porcellus) is shorter and RT less homologous than apolipoprotein CIII from other mammals."; RL Comp. Biochem. Physiol. 124B:157-161(1999). CC -!- FUNCTION: Inhibits lipoprotein lipase and hepatic lipase and CC decreases the uptake of lymph chylomicrons by hepatic cells. This CC suggests that it delays the catabolism of triglyceride-rich CC particles (By similarity). CC -!- SUBCELLULAR LOCATION: Secreted. CC -!- TISSUE SPECIFICITY: Mainly VLDL and also in HDL. Synthesized CC predominantly in liver and to a lesser degree in intestine. CC -!- SIMILARITY: Belongs to the apolipoprotein C3 family.
