Description			Precursor of the egg-yolk proteins that are sources of nutrients during early development of oviparous organisms. Phosvitin is believed to be of importance in sequestering calcium, iron and other cations for the developing bryo. Source: Recombinant protein corresponding to 24-633 from chicken VTG1, fused to His-Tag at N-terminal, expressed in E.coli.
