Usp29 (ubiquitin-specific processing protease 29, Ocat) is expressed mainly from the paternal
allele. It is expressed in the adult brain, and in embryonic forebrain, face and limb buds (Kim
al, 2000; Szeto IYY et al, 2000).
Imprinted paternal expression of Usp29 was confirmed in placenta (Wang X et al, 2011 and Okae H et al, 2012 ).
