General annotation (Comments)

Function

Constitutes the major component of lipophorin, which mediates transport for various types of lipids in hemolymph. Acts by forming lipoprotein particles that bind lipoproteins and lipids. May be required for morphogens wingless (wg) and hedgehog (hh) function, possibly by acting as vehicles for the movement of wg and hh By similarity.

Subcellular location

Secreted.

Tissue specificity

Present in brain, hemolymph, fat body and eyes. Ref.1

Post-translational modification

Cleaved into 2 chains by furin protease. However, prevention of cleavage does not impair its function.

N-glycosylated By similarity.

Sequence similarities

Contains 1 vitellogenin domain.

Contains 1 VWFD domain.
