Given a passage with a question and an answer to that question, classify if the answer actually answers the question into 'yes' or 'no'. Output 'yes' if the answer answers the question and output 'no' if the answer does not answer the question.

Question: Does a specific binding site for the prorenin propart peptide Arg10-Arg20 occur on human endothelial cells?
Answer: The binding of the human prorenin peptide RIFLKRMPSIR to HUVEC proteins is not specific for amino acid sequence and probably involves a general peptide/protein uptake mechanism. We could not detect a specific prorenin propart binding site in these cells.
no
