PRO

PRO provides an ontological representation of protein-related entities by explicitly defining them and showing the relationships between them. Each PRO term represents a distinct class of entities (including specific modified forms, orthologous isoforms, and protein complexes) ranging from the taxon-neutral to the taxon-specific.

PRO（蛋白质本体，Protein Ontology）通过明确定义蛋白质相关实体并清晰阐释其间的相互关系，实现了对这些实体的本体论表征。每个PRO术语均代表一类独特的实体类别，其覆盖范围从分类群中性到分类群特异性，涵盖特定修饰形式、直系同源异构体以及蛋白质复合物。
