An objective of the present invention is to provide antigen-binding molecules whose antigen-binding activity changes depending on the concentration of a small molecule compound specific to a target tissue, polynucleotides encoding the antigen-binding molecules, vectors containing the polynucleotides, cells carrying the vectors, libraries containing a plurality of the antigen-binding molecules that are different from one another, pharmaceutical compositions containing the antigen-binding molecules, methods of screening for the antigen-binding molecules, methods of producing the same, and the like. The present inventors discovered methylthioadenosine (MTA) as a small molecule compound specific to tumor tissue and created an antigen-binding domain whose antigen-binding activity changes depending on the concentration of MTA, or an antigen-binding molecule containing the antigen-binding domain, and also created a library containing a plurality of antigen-binding domains or antigen-binding molecules containing the antigen-binding domains that are different from one another and discovered that the above objective can be achieved by using the library. By using the antigen-binding molecules of the present disclosure, various diseases (for example, cancer) caused by target tissues (for example, tumor tissues) can be treated in a target tissue-specific manner.
