Three‐dimensional structures of avian beta‐microseminoproteins: insight from the chicken egg‐specific beta‐microseminoprotein 3 paralog

FEBS Open Bio, 2021
Beta‐microseminoproteins (MSMBs) are small disulfide‐rich proteins that are conserved among vertebrates. These proteins exhibit diverse biological activities and were mainly reported to play a role in male fertility, immunity, and embryogenesis.
