Research AreasSignal Transduction

Function

Phosvitin is believed to be of importance in sequestering calcium, iron and other cations for the developing embryo.

Biological Context

Tissue Specificity: After incorporation from serum via a specific receptor, it is cleaved into four fragments, heavy and light chain lipovitellins, phosphovitin and YGP40, and YGP40 is released into the yolk plasma before or during compartmentation of lipovitellin-phosvitin complex into the yolk granule
