RT   "The amino acid sequence of a protein (apovitellenin I) from the low-
RT   density lipoprotein of emu egg yolk.";
RL   Aust. J. Biol. Sci. 27:15-21(1974).
CC   -!- FUNCTION: Protein component of the very low density lipoprotein (VLDL)
CC       of egg-laying females. Potent lipoprotein lipase inhibitor, preventing
CC       the loss of triglycerides from VLDL on their way from the liver to the
CC       growing oocytes.
CC   -!- SUBUNIT: Monomer. {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the apovitellenin family. {ECO:0000305}.
