Interactioni

Subunit structurei

Prostatein is composed of three different peptides called C1, C2 and C3. These form covalent C1:C3 (F) and C2:C3 (S) heterodimers whose non-covalent association forms tetrameric (C1:C3/C3:C2) prostatein molecules.

100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
