Cloning of a novel epidermal growth factor repeat containing gene EGFL6: expressed in tumor and fetal tissues.
The epidermal growth factor (EGF) repeat superfamily of genes often encodes proteins that govern cellular proliferative responses. Using a high-throughput screening by hybridization approach, a novel human EGF repeat superfamily member that maps to human chromosome X was identified. Termed EGFL6, the gene encodes a predicted signal peptide, suggesting that it is secreted. Other predicted features include four and one-half EGF-like repeat domains, two N-linked glycosylation sites, an integrin association motif (RGD), and a tyrosine phosphorylation site. Importantly, its transcripts are expressed in brain and lung tumor and fetal tissues, but are generally absent from normal adult tissues. Implications with respect to cell cycle regulation and oncogenesis are discussed.
