Claim 5:
6. The polypeptide of claim 1, wherein said ectodomain comprises or consists of an amino acid sequence having at least 80%, at least 90% or at least 95% sequence identity with the amino acid sequence of SEQ ID NO:1,
and wherein said ectodomain has
at amino acid position 282 an amino acid residue other than an arginine residue and/or
at amino acid position 286 an amino acid residue selected from the group consisting of lysine residue, leucine residue, isoleucine residue, valine residue and tryptophan residue and/or
at amino acid position 287 a lysine residue,

and has
at amino acid position 309 an amino acid residue other than an arginine residue and/or
at amino acid position 313 an amino acid residue selected from the group consisting of lysine residue, leucine residue, isoleucine residue, valine residue and tryptophan residue and/or,
at amino acid position 314 a lysine residue,

wherein the numbering of the amino acid positions refers to the amino acid sequence of SEQ ID NO:1.
