CO OZNACZA SŁOWO PROTAMINE
Protamina
Protaminy są niewielkimi, bogatymi w argininę białkami jądrowymi, które zastępują histony późną fazą spajania komórek macierzystych i uważane są za istotne dla kondensacji głowy nasienia i stabilizacji DNA. Mogą pozwolić na gęstsze opakowanie DNA w spermatozoonie niż histony, ale muszą być rozpakowane zanim dane genetyczne mogą być wykorzystane do syntezy białek. Jednak u ludzi, a może i innych naczelnych, 10-15% genomu plemnika pakowane jest przez histony, które uważają, że wiążą się z genami, które są istotne dla wczesnego rozwoju zarodkowego.
