Product Description

Protease inhibitor required for egg fertilization. Required to prevent premature zona pellucida hardening before fertilization, probably by inhibiting the protease activity of ASTL, a protease that mediates the cleavage of ZP2 and triggers zona pellucida hardening. Source: Recombinant protein corresponding to aa19-378 from rat Fetub, fused to His-Tag at N-terminal, expressed in Yeast.
