EGFL7 is a secreted protein that contains one Emilin-like (EMI) domain and two epidermal growth factor (EGF) domains - one of which binds calcium. Based on these domains, it has been hypothesized that EGFL7 may self-assemble like extracellular matrix (ECM) proteins and, thereby, incorporate into the ECM. EGFL7 has been reported to stimulate cell adhesion as well as motility in a manner similar to ECM proteins. While primarily expressed by developing ECs, EGFL7 is also known to be expressed by primordial germ cells and some central nervous system neurons. Interestingly, EGFL7 expression markedly decreases in ECs in postnatal life, but can be strongly up-regulated after various tissue injuries that lead to increased angiogenic responses. DNA sequence spanning the mature chain of Mouse EGFL7(VE-Statin) isoform-1 (and inclusive of a C-terminal polyHis tag) was expressed in Insect cells. Recombinant Mouse EGFL7 is a monomer (273 residues) that migrates at approximately 33 kDa under reducing conditions in an SDS-PAGE.
