C, impact of FK506 on the refolding of full-length type III collagen monitored by CD at 220 nm. The protein concentrations had been 0.two and two.0 M for full-length variety III collagen and FKBP22, respectively. FKBP22 was preincubated with ten M FK506 for 5 min at room temperature. Refolding of type III collagen with DMSO is shown within the presence (blue) and absence (black) of FKBP22 or with FK506 inside the presence (green) and absence (red) of FKBP22. FKBP22 alone with DMSO (magenta) and with FK506 (cyan) are also shown.JUNE 27, 2014 ?VOLUME 289 ?NUMBERJOURNAL OF BIOLOGICAL CHEMISTRYFKBP22 Preferentially Recognizes Kind III, VI, and X CollagenFIGURE 8. Direct binding kinetics of FKBP22 to collagens. Direct binding kinetics have been monitored by surface plasmon resonance analysis employing a BIAcore X instrument. A, 40 M FKBP22 (red) and 0.05 M Hsp47 (blue) as positive control were injected over a CM5 chip with immobilized bovine type I collagen. B, 25 M FKBP22 (red) and 0.1 M Hsp47 (blue) as good control had been injected over a CM5 chip with immobilized bovine kind II collagen. C, 60 M FKBP22 (red) and 0.05 M Hsp47 (blue) as good handle were injected more than a CM5 chip with immobilized bovine variety III collagen. D, 30 M FKBP22 (red) and 0.3 M Hsp47 (blue) as positive control were injected more than a CM5 chip with immobilized bovine variety V collagen. E, 30 M FKBP22 (red) and 0.3 M Hsp47 (blue) as constructive handle had been injected more than a CM5 chip with immobilized human type VI collagen. F, 24 M FKBP22 (red) and 0.four M Hsp47 (blue) as optimistic handle were injected more than CM5 chip-immobilized human type X collagen. G, several concentrations of FKBP22 have been run over the type III collagen chip.1783624-20-3 web The following binding curves are shown: 60 M (black), 40 M (red), 30 M (blue), and 20 M (green) FKBP22. H, several concentrations of FKBP22 had been run over the form VI collagen chip. The following binding curves are shown: 30 M (black), 24 M (red), 18 M (blue), and 12 M (green) FKBP22. I, various concentrations of FKBP22 had been run over the type X collagen chip. The following binding curves are shown: 24 M (black), 16 M (red), 12 M (blue), and 8 M (green) FKBP22.TABLE four Binding of Hsp47 and FKBP22 to several forms of collagenkamskds1KdMvalue six.5 1.7 two.Form I collagen Type II collagen Sort III collagen Sort Vcollagen Type VI collagen Type X collagena b cHsp47a Hsp47 (63) FKBP22 Hsp47a Hsp47 (63) FKBP22 Hsp47a Hsp47 (63) FKBP22a Hsp47a Hsp47 (63) FKBP22 Hsp47a FKBP22c Hsp47a FKBP22c1.four 1.24 104 2.08 104 18.6 12 104 2.38 104 11.9 1.0 104 2.18 104 4.9 0.7 104 10.0 3.11 104 1.89 104 13.9 11.9 9.01 104 113.1 two.6 ten 2.36 10 2 five.3 0.38 ten 1.71 102.eight 0.BuyAzido-PEG3-alcohol 38 10 two 1.PMID:35126464 55 10 two three.four 0.five 10 two two.4 0.05 10 two 1.65 ten 2 two.four 9.three 0.01 ten 1.924.08 2.eight 1.1 NOb 0.406 0.24 0.71 NO 0.24 0.1 0.71 69 1.7 0.24 0.08 0.87 NO 0.21 0.14 62 46 1.six 1.2 4312.eight 8.2 14.12.five 6.three four.7 1.5 9.7 0.7 ten.4 four.3 six.three 1.0 four.6 three.Information had been calculated by a international match from the concentration-dependent measurements employing the Langmuir model.

FKBP22 binds to kind X collagen but not form II collagen. This result suggests that FKBP22 is involved in the development of the hypertrophic zone in cartilage, abundant in sort X collagen, but not in development of articular cartilage, abundant in kind II collagen. Joint hypermobility is observed in these individuals, a.
