Centrins are members of the EF-hand family of calcium-binding proteins, which are highly conserved among eukaryotes. Centrins bind to several cellular targets, through a hydrophobic triad. However, the W(1)xxL(4)xxxL(8) triad in XPC (Xeroderma Pigmentosum Group C protein) is found in the reverse orientation, as in the L(8)xxxL(4)xxW(1) triad in Sfi1(More)
Centrins are calcium-binding proteins that can interact with several cellular targets (Sfi1, XPC, Sac3 and transducin β) through the same hydrophobic triad. However, two different orientations of the centrin-binding motif have been observed: W(1)xxL(4)xxxL(8) for XPC (xeroderma pigmentosum group C protein) and the opposite orientation L(8)xxxL(4)xxW(1) for(More)
The Ca(2+)-binding protein centrin binds to a hydrophobic motif (W(1)xxL(4)xxxL(8)) included in the sequence of several cellular targets: XPC (xeroderma pigmentosum group C protein), Sfi1 (suppressor of fermentation-induced loss of stress resistance protein1), and Sac3 [the central component of the transcription and mRNA export (TREX-2) complex]. However,(More)
The optimum conditions for the formation of plate-like and urchin-like microcrystals of biomolecules and their transfer to rotors for solid-state NMR spectroscopy depend on a variety of factors, of which minimizing the manipulation of the microcrystals and storing the sample for several months at 277 K (4 °C) play an important role.
