001package org.biopax.paxtools.model.level3; 002 003/** 004 * <b>Description:</b> A protein reference is a grouping of several protein entities that are encoded by the same 005 * genetic sequence. Members can differ in any combination of cellular location, sequence features and bound partners. 006 * 007 * <b>Rationale:</b> Protein molecules, encoded by the same genetic sequence can be present in (combinatorially many) 008 * different states, as a result of post translational modifications and non-covalent bonds. Each state, chemically, is 009 * a different pool of molecules. They are, however, related to each other because: 010 * 011 * <ul> <li> They all share the same "base" genetic sequence. </li> <li> They can only be converted to each other but 012 * not to any other protein</li> </ul> 013 * 014 * <b>Comments:</b>Most Protein databases, including UniProt would map one to one with ProteinReferences in BioPAX. 015 */ 016public interface ProteinReference extends SequenceEntityReference { 017}
