ECOP (EGFR-coamplified and overexpressed protein), also known as VOPP1 (vesicular, overexpressed in cancer, prosurvival protein 1) or GASP (glioblastoma-amplified secreted protein), is a 172 amino acid protein that is coamplified with EGFR and overexpressed in multiple glioblastomas. Highly expressed in ovary and thymus, ECOP is found at moderate levels in testis, colon, small intestine, and spleen, and at low levels in liver, placenta and prostate. ECOP regulates NF˚B signaling and may have a role in resistance to apoptosis. The gene encoding ECOP maps to human chromosome 7, which houses over 1,000 genes, comprises nearly 5% of the human genome and has been linked to Osteogenesis imperfecta, Pendred syndrome, Lissencephaly, Citrullinemia and Shwachman-Diamond syndrome. |
