Summary

NOL8 (nucleolar protein 8, HGNC:23387) is a protein-coding gene on chromosome 9q22.31, encoding Nucleolar protein 8 (Q76FK4). Plays an essential role in the survival of diffuse-type gastric cancer cells. It is a common-essential gene (DepMap: required in 90.6% of cancer cell lines).

NOL8 binds Ras-related GTP-binding proteins (see MIM 608267) and plays a role in cell growth (Sekiguchi et al., 2004 [PubMed 14660641]).
