Abstract
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.
Claims2
A chimera protein which has any of the amino acid sequences shown below:
- (A) the amino acid sequence as shown in SEQ ID NO 15;
- or
- (B) the amino acid sequence as shown in SEQ ID NO:
- 15, in which one to ten amino acids are deleted, substituted, and/or added, and which has an activity of growing vascular endothelial cells.
A chimera protein having the amino acid sequence of SEQ ID NO:
- 15, in which one to five amino acids are deleted, substituted, and/or added, and which has an activity of growing vascular endothelial cells.
