Chimeric human-type vascular endothelial cell growth factor

摘要

An object of the present invention is to provide a chimera VEGF-E having a reduced antigenicity while maintaining the activity of VEGF-E. The present invention provides a chimera protein having an activity of growing vascular endothelial cells, which is obtained by substituting a part of the sequence of a VEGF analogous protein having an activity of vascularization that binds to KDR (VEGF receptor-2) but does not bind to Flt-1 (VEGF receptor-1) with a corresponding sequence of a human-derived VEGF analogous protein.
