NAP1L5 (nucleosome assembly protein 1-like 5) was expressed in pig pituitary, liver, spleen, lung,
kidney, stomach, small intestine, skeletal muscle, fat, ovary, and uterus, but undetectable in the
heart. "The paternal allele was expressed in the 11 tissues where the gene expression was
detectable" (Jiang CD et al, 2011).
It also showed expression of the paternal allele in one informative pig placenta (Gu T et al, 2011).
