B, D	PF00031	Cystatin domain (Cystatin)	Cystatin domain	Very diverse family. Attempts to define separate sub-families failed. Typically, either the N-terminal or C-terminal end is very divergent. But splitting into two domains would make very short families. All members except Swiss:Q03196 and Swiss:Q1 ...	Very diverse family. Attempts to define separate sub-families failed. Typically, either the N-terminal or C-terminal end is very divergent. But splitting into two domains would make very short families. All members except Swiss:Q03196 and Swiss:Q10993 are found. Pfam:PF00666 are related to this family but have not been included.	Domain
