PBID Uniprot Name Gene Alternative Organism Uniprot Description
PB0049 P06727 Apolipoprotein A-IV APOA4 apolipoprotein A4 Homo_sapiens May have a role in chylomicrons and VLDL secretion and catabolism. Required for efficient activation of lipoprotein lipase by ApoC-II; potent activator of LCAT. Apoa-IV is a major component of HDL and chylomicrons.
