16363816 Thorn DC, Meehan S, Sunde M, Rekas A, Gras SL, MacPhee CE, Dobson CM, Wilson MR, Carver JA: Amyloid fibril formation by bovine milk kappa-casein and its inhibition by the molecular chaperones alphaS- and beta-casein. Biochemistry. 2005 Dec 27;44(51):17027-36.

The time-dependent increase in thioflavin T fluorescence observed for reduced and nonreduced kappa-casein at 37 degrees C was suppressed by stoichiometric amounts of alphaS- and beta-casein and by the hydrophobic dye 8-anilino-1-naphthalene sulfonate; the inhibition of kappa-casein fibril formation under these conditions was verified by TEM.

Furthermore, binding experiments with the common hydrophobic probe - 8-anilino-1- naphthalene sulfonic acid (ANS) illustrated that beta-CN-(f1-192) is nearly incapable of binding to ANS relative to whole beta-CN, suggesting a nearly complete open overall tertiary structure brought about by the C-terminal truncation.

Naphthalene-2,3-dicarboxaldehyde (NDA), a fluorescence derivatization reagent, was used to label protein hydrolysate.
With beta-casein as the analysis protein, this method was successfully validated.

Both fluorescence and DLS studies showed greater propensity for micellisation of the dimeric beta-CNs, suggesting that the factors inducing the formation of micelles are stronger in the bi-amphiphilic dimers. 1-anilino-naphthalene-8-sulfonate (ANS) binding studies showed different binding of ANS by these dimers as well as different exposition of ANS binding (hydrophobic) regions in the micellar states.
Bovine beta-casein (beta-CN) is a highly amphiphilic micellising phospho-protein showing chaperone-like activity in vitro.
