Pinc
Pinc (pregnancy induced noncoding RNA) is a long non-coding RNA. It was originally identified in the mammary glands of oestrogen and progesterone-treated rats. Pinc may be a mammal-specific gene. It is conserved in a number of mammalian genomes (human, mouse, rat, chimpanzee, dog, cow and opossum), but not in fugu, zebrafish or xenopus genomes.
