PB0085 | Q9UGM5 | Fetuin-B | FETUB | 16G2, Gugu, IRL685 | Homo_sapiens | 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. |
