Comparison of the primary structures of the KIR2DL5A*001 and *005 D2 Ig-like domains, along with those of KIR2DL1 alleles *001 and *014, and KIR2DL4*001. Arrows mark KIR2DL5A polymorphic positions 152 and 174, and Phe-129, predictably confronted to Gly/Ser-174 in the receptor architecture. Other residues mentioned in the text are underlined. Amino acid numbering is based on the mature KIR2DL5A polypeptide (the KIR2DL1 N-terminal Ig-like domain, not represented, is five amino acids longer than those of killer-cell Ig-like receptors 2DL4 and 2DL5).
