Small proteins of up to ∼50 amino acids play important physiological roles across all domains of life. Mass spectrometry is an ideal approach to detect and characterize small proteins, but many aspects of standard mass spectrometry workflows are biased against small proteins due to their size. Here, we highlight applications of mass spectrometry to study small proteins, emphasizing modifications to standard workflows to optimize the detection of small proteins.
