basic FUNCTION	playing a role in maternal imprinting may be dependent or facilitated by the presence of a nuclear matrix attachment region (MAR)
	containing a promoter region playing a critical role in the initiation of imprint switching during spermatogenesis
	time-dependent demethylated during the process of postovulatory aging in oocytes (Liang 2008)
