| 摘要 |
The invention relates to a peptide domain required for interaction between the envelope of a virus pertaining to the HERV-W interference group and a hASCT receptor, comprising an N end point and a C end point. Said peptide domain is defined, at the N end point thereof, by a pattern formed by the amino acids L (Z)-proline-cysteine-X-cysteine in which Z is any amino acid, is a whole number between 2 and 30, and X is any amino acid, and at the C end point thereof, by a pattern formed by the amino acids serine-aspartic acid-Xa-Xb-Xc-Xd-Xe-aspartic acid-Xf-Xg-(Z) in which Xa, Xb, Xc, Xd, Xe, Xf, Xg are any amino acids, Z is any amino acid, B is a whole number between 15 and 25, preferably 20. The peptide domain comprises, between the N end point and the C end point, at least one pattern selected from the following patterns: a pattern formed by the amino acids cysteine-X2-X3-X4-X5-X6-cysteine in which X2, X3, X4, X5, X6 are any amino acids, and a pattern formed by the amino acids cysteine-X7-X8-X9-X10-X11-X12-X13-X14-X15-cysteine-trytophane in which X7, X8, X9, X10, X11, X12, X13, X14, X15 are any amino acids. |
