Paternally-expressed gene 3 protein is a protein that in humans is encoded by the Peg3 gene.^[1][2] Peg3 is an imprinted gene expressed exclusively from the paternal allele and plays important roles in controlling fetal growth rates and nurturing behaviors as has potential roles in mammalian reproduction.^[3] PEG3 is a transcription factor that binds to DNA [11-13] via the sequence motif AGTnnCnnnTGGCT, which it binds to using multiple Kruppel-like factors. It also regulate the expression of Pgm2l1 through the binding of the motif.^[4]

Interactions

PEG3 has been shown to interact with SIAH2^[5] and SIAH1.^[5]
