CC   -!- FUNCTION: May possess a function in tumorigenesis.
CC   -!- SUBCELLULAR LOCATION: Nucleus. Note=When overexpressed.
CC   -!- TISSUE SPECIFICITY: Transcript detectable in many tumor cell lines and
CC       tumor tissues.
CC   -!- MISCELLANEOUS: Protein expressed at very low level.
CC   -!- MISCELLANEOUS: This Np9 protein is encoded by a human specific
CC       provirus.
CC   -!- MISCELLANEOUS: Has a type 1 genome. The HERV-K(HML-2) family contains
CC       type 1 and type 2 genomes depending on the absence or presence of 292
CC       nucleotides at the 5'-end of the env gene. Np9 proteins are translated
CC       from a doubly spliced transcript expressed exclusively by HERV-K(HML-2)
CC       type 1 proviral genomes. Np9 proteins share 14 N-terminal amino acids
CC       with HERV-K(HML-2) type 2 envelope proteins. The rest of the protein is
CC       encoded by a small exon located at the 3' end of the envelope gene.
CC       This exon shares the same splice acceptor site and therefore overlaps
CC       HERV-K(HML-2) type 2 Rec protein second exon. It is yet translated from
CC       an alternate reading frame.
CC   -!- MISCELLANEOUS: Intergenic, closest flanking gene being PRODH.
