Plagl1 (pleiomorphic adenoma gene-like 1; Zac1 - zinc finger protein regulator of apoptosis and cell
cycle arrest) is expressed exclusively from the paternal allele in all fetal and adult mouse tissues
G et al, 2000; Smith
RJ et al, 2002). Piras et al. reported bialleic expression in the liver.
Orthologous to the human imprinted gene PLAGL1/ZAC/LOT1.
