Proposed Schematic Structure for Eutherian and Metatherian P1 Type Protamines. Highly conserved positions highlighted and overlaid onto proposed schematic structures for Bos taurus (Bull) and Macropus rufus (Red Kangaroo) sperm protamine P1s. Schematic structure of Bull P1 sperm protamines based off of Balhorn 1991 [13]. Red Kangaroo schematic structure assumed from similarity
