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   -!- TISSUE SPECIFICITY: Found in egg yolk and in plasma.
CC   -!- SIMILARITY: Belongs to the apovitellenin family. {ECO:0000305}.
