Characterization of human sperm protamine proteoforms through a combination of top-down and bottom-up mass spectrometry approaches

Protamine 1 (P1) and protamine 2 (P2) family are extremely basic, sperm-specific proteins, packing 85-95% of the paternal DNA. P1 is synthesized as a mature form, whereas P2 components (HP2, HP3, and HP4) arise from the proteolysis of the precursor (pre-P2). Due to the particular protamine physical-...
