Integrated In Silico-In Vitro Identification and Optimization of Bone Morphogenic Protein-2 Armpit Epitope as Its Antagonist Binding Site

Abstract Bone morphogenic protein-2 (BMP-2) is the most documented member of BMP family and plays a crucial role in bone formation and growth. In this study, we systematically analyze and compare the complex crystal structures and interaction properties of BMP-2 with its cognate receptors BMPR-I/BMP...

520			\|a Abstract Bone morphogenic protein-2 (BMP-2) is the most documented member of BMP family and plays a crucial role in bone formation and growth. In this study, we systematically analyze and compare the complex crystal structures and interaction properties of BMP-2 with its cognate receptors BMPR-I/BMPR-II and with its natural antagonist crossveinless-2 (CV-2) using an integrated in silico-in vitro strategy. It is found that the antagonist-binding site is not fully overlapped with the two receptor-binding sites on BMP-2 surface; the antagonist can competitively disrupt BMP-2–BMPR-II interaction using a blocking-out-of-site manner, but has no substantial influence on BMP-2–BMPR-I interaction. Here, the antagonist-binding site is assigned as a new functional epitope armpit to differ from the traditional conformational epitope wrist and linear epitope knuckle at receptor-binding sites. Structural analysis reveals that the armpit comprises three sequentially discontinuous, structurally vicinal peptide segments, separately corresponding to a loop region and two β-strands crawling on the protein surface. The three segments cannot work independently when splitting from the protein context, but can restore binding capability to CV-2 if they are connected to a single peptide. A systematic combination of different-length polyglycine linkers between these segments obtains a series of designed single peptides, from which several peptides that can potently interact with the armpit-recognition site of CV-2 with high affinity and specificity are identified using energetic analysis and fluorescence assay; they are expected to target BMP-2–CV-2 interaction in a self-inhibitory manner.

In this study, we systematically analyze and compare the complex crystal structures and interaction properties of BMP-2 with its cognate receptors BMPR-I/BMPR-II and with its natural antagonist crossveinless-2 (CV-2) using an integrated in silico-in vitro strategy. It is found that the antagonist-binding site is not fully overlapped with the two receptor-binding sites on BMP-2 surface; the antagonist can competitively disrupt BMP-2–BMPR-II interaction using a blocking-out-of-site manner, but has no substantial influence on BMP-2–BMPR-I interaction. Here, the antagonist-binding site is assigned as a new functional epitope armpit to differ from the traditional conformational epitope wrist and linear epitope knuckle at receptor-binding sites. Structural analysis reveals that the armpit comprises three sequentially discontinuous, structurally vicinal peptide segments, separately corresponding to a loop region and two β-strands crawling on the protein surface. The three segments cannot work independently when splitting from the protein context, but can restore binding capability to CV-2 if they are connected to a single peptide. A systematic combination of different-length polyglycine linkers between these segments obtains a series of designed single peptides, from which several peptides that can potently interact with the armpit-recognition site of CV-2 with high affinity and specificity are identified using energetic analysis and fluorescence assay; they are expected to target BMP-2–CV-2 interaction in a self-inhibitory manner.

In this study, we systematically analyze and compare the complex crystal structures and interaction properties of BMP-2 with its cognate receptors BMPR-I/BMPR-II and with its natural antagonist crossveinless-2 (CV-2) using an integrated in silico-in vitro strategy. It is found that the antagonist-binding site is not fully overlapped with the two receptor-binding sites on BMP-2 surface; the antagonist can competitively disrupt BMP-2–BMPR-II interaction using a blocking-out-of-site manner, but has no substantial influence on BMP-2–BMPR-I interaction. Here, the antagonist-binding site is assigned as a new functional epitope armpit to differ from the traditional conformational epitope wrist and linear epitope knuckle at receptor-binding sites. Structural analysis reveals that the armpit comprises three sequentially discontinuous, structurally vicinal peptide segments, separately corresponding to a loop region and two β-strands crawling on the protein surface. The three segments cannot work independently when splitting from the protein context, but can restore binding capability to CV-2 if they are connected to a single peptide. A systematic combination of different-length polyglycine linkers between these segments obtains a series of designed single peptides, from which several peptides that can potently interact with the armpit-recognition site of CV-2 with high affinity and specificity are identified using energetic analysis and fluorescence assay; they are expected to target BMP-2–CV-2 interaction in a self-inhibitory manner.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Bone morphogenic protein-2</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Antagonist</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">epitope</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Peptide</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Molecular recognition</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Jia, Guanghong</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Chi, Haiyan</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Jiao, Zhaode</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Sun, Yinghua</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">The protein journal</subfield><subfield code="d">Dordrecht : Springer Science + Business Media B.V., 2004</subfield><subfield code="g">39(2020), 6 vom: 01.

abstract	Abstract Bone morphogenic protein-2 (BMP-2) is the most documented member of BMP family and plays a crucial role in bone formation and growth. In this study, we systematically analyze and compare the complex crystal structures and interaction properties of BMP-2 with its cognate receptors BMPR-I/BMPR-II and with its natural antagonist crossveinless-2 (CV-2) using an integrated in silico-in vitro strategy. It is found that the antagonist-binding site is not fully overlapped with the two receptor-binding sites on BMP-2 surface; the antagonist can competitively disrupt BMP-2–BMPR-II interaction using a blocking-out-of-site manner, but has no substantial influence on BMP-2–BMPR-I interaction. Here, the antagonist-binding site is assigned as a new functional epitope armpit to differ from the traditional conformational epitope wrist and linear epitope knuckle at receptor-binding sites. Structural analysis reveals that the armpit comprises three sequentially discontinuous, structurally vicinal peptide segments, separately corresponding to a loop region and two β-strands crawling on the protein surface. The three segments cannot work independently when splitting from the protein context, but can restore binding capability to CV-2 if they are connected to a single peptide. A systematic combination of different-length polyglycine linkers between these segments obtains a series of designed single peptides, from which several peptides that can potently interact with the armpit-recognition site of CV-2 with high affinity and specificity are identified using energetic analysis and fluorescence assay; they are expected to target BMP-2–CV-2 interaction in a self-inhibitory manner.
