Slc22a2 (solute carrier family 22 (organic cation transporter), member 22; Oct2; Ocrt2), is
maternally expressed in the placenta. There is partial paternal repression in the adult kidney (Zwart
R et al, 2001).
Imprinted expression of Slc22a2 was confirmed in visceral yolk sac (Hudson QJ et al, 2011).
Slc22a2 imprinting requires the presence of the imprinted paternally expressed Air RNA (Sleutels
F et al, 2002; Sleutels
F et al 2003).
