Claims (20)

1. A recombinant AdB-2/3 fiber polypeptide homotrimer, wherein each member of the homotrimer comprises: (a) one or more AdB-2/3 fiber polypeptide shaft domain motifs; (b) an AdB-2/3 fiber polypeptide knob domain operatively linked to and located C-terminal to the one or more AdB-2/3 fiber polypeptide shaft domain motifs, wherein the AdB-2/3 fiber polypeptide knob domain comprises the peptide of SEQ ID NO:4 wherein: X2 is H, L, or P; X3 is K or E; X4 is T, F, S, or L; X5 is V, or D; X6 is E or G; X7 is Y or F; X8 is T, K, or E; and X9 is N or S; and wherein at least one of the following is true: X2 is P; X3 is E; X4 is S, or L; X5 is D; X6 is G; X7 is F; X8 is E; or X9 is S; and (c) one or more non-AdB-2/3-derived dimerization domains operatively linked to and located N-terminal to the one or more AdB-2/3 fiber polypeptide shaft domain motifs.

2. The recombinant AdB-2/3 fiber polypeptide homotrimer of claim 1 , wherein the AdB-2/3 fiber polypeptide knob domain comprises the peptide selected from the group consisting of SEQ ID NOS: 5-11.

3. The recombinant AdB-2/3 fiber polypeptide homotrimer of claim 1 , wherein the AdB-2/3 fiber polypeptide knob domain comprises the peptide of SEQ ID NO:8.

4. The recombinant AdB-2/3 fiber polypeptide homotrimer of claim 1 , wherein the AdB-2/3 fiber polypeptide does not include an AdB-2/3 fiber polypeptide tail domain.

5. The recombinant AdB-2/3 fiber polypeptide homotrimer of claim 1 , wherein each shaft domain motif is selected from the group consisting of an Ad3 fiber polypeptide shaft domain motif, an Ad7 fiber polypeptide shaft domain motif, an Ad11 fiber polypeptide shaft domain motif, an Ad14 fiber polypeptide shaft domain motif, an Ad14a fiber polypeptide shaft domain motif, and combinations thereof.

6. The recombinant AdB-2/3 fiber polypeptide homotrimer of claim 1 , wherein the one or more shaft domain motifs comprise 1-22 shaft domain motifs.

7. The recombinant AdB-2/3 fiber polypeptide homotrimer of claim 1 , wherein each shaft domain motif comprises an amino acid sequence selected from the group consisting of SEQ ID NOS: 43-48.

8. The recombinant AdB-2/3 fiber polypeptide homotrimer of claim 1 , wherein the dimerization domain comprises an amino acid sequence selected from the group consisting of EVSALEK (SEQ ID NO:24) and/or KVSALKE (SEQ ID NO: 25).

9. The recombinant AdB-2/3 fiber polypeptide homotrimer of claim 1 , wherein the one or more shaft domain motifs are the shaft domain motif of SEQ ID NO:43.

10. The recombinant AdB-2/3 fiber polypeptide homotrimer of claim 1 , wherein the AdB-2/3 fiber polypeptide contains a single AdB-2/3 fiber polypeptide shaft domain motif.

11. The recombinant AdB-2/3 fiber polypeptide homotrimer of claim 1 , comprising a homotrimer of the amino acid sequence selected from the group consisting of SEQ ID NO: 28, SEQ ID NO: 29, SEQ ID NO: 30, SEQ ID NO: 31, SEQ ID NO: 32, SEQ ID NO: 33, and SEQ ID NO: 34.

12. The recombinant AdB-2/3 fiber polypeptide of claim 1 , wherein the AdB-2/3 fiber polypeptide homotrimer is a dimer of the homotrimer.

13. The recombinant AdB-2/3 fiber polypeptide of claim 2 , wherein the AdB-2/3 fiber polypeptide homotrimer is a dimer of the homotrimer.

14. The recombinant AdB-2/3 fiber polypeptide of claim 3 , wherein the AdB-2/3 fiber polypeptide homotrimer is a dimer of the homotrimer.

15. The recombinant AdB-2/3 fiber polypeptide of claim 7 , wherein the AdB-2/3 fiber polypeptide homotrimer is a dimer of the homotrimer.

16. The recombinant AdB-2/3 fiber polypeptide of claim 11 , wherein the AdB-2/3 fiber polypeptide homotrimer is a dimer of the homotrimer.

17. The recombinant AdB-2/3 fiber polypeptide homotrimer of claim 1 , further comprising one or more compounds conjugated to the recombinant AdB-2/3 fiber polypeptide, wherein the one or more compounds are selected from the group consisting of therapeutics, diagnostics, and imaging agents.

18. The recombinant AdB-2/3 fiber polypeptide homotrimer of claim 17 , wherein the one or more compounds comprise at least one therapeutic, wherein the therapeutic is selected from the group consisting of antibodies, immunoconjugates, nanoparticles, chemotherapeutics, radioactive particles, viruses, vaccines, cellular immunotherapy therapeutics, gene therapy constructs, nucleic acid therapeutics, and combinations thereof.

19. A pharmaceutical composition, comprising (a) the AdB-2/3 fiber polypeptide homotrimer of claim 12 , and (b) a pharmaceutically acceptable carrier.

20. A pharmaceutical composition, comprising (a) a dimer of the AdB-2/3 fiber polypeptide homotrimer of claim 17 and (b) a pharmaceutically acceptable carrier.
