Cysteine 7-15 FKBP prolyl isomerase 1B Homo sapiens 96-104 19258192-6 2009 The slow refolding step could be partly attributed to proline isomerization, based on an increased rate during refolding in the presence of PPIase and an increased relative amplitude of this step with increasing delay time in double-jump refolding experiments observed over delays of 5-100 s. However, double-jump refolding experiments with delay times longer than 100 s along with size exclusion chromatography and dynamic light scattering of refolding samples showed that the overall refolding yield decreased as bhx was unfolded for longer periods of time. Proline 54-61 FKBP prolyl isomerase 1B Homo sapiens 140-146 17606610-3 2007 Hyperphosphorylation at a single amino acid residue, Ser-2808, has been proposed to directly disrupt the binding of a 12.6-kDa FK506-binding protein (FKBP12.6) to RyR2, causing a RyR2 malfunction that triggers cardiac arrhythmias in human heart failure.

Diamide 22-29 FKBP prolyl isomerase 1B Homo sapiens 63-71 17200109-9 2007 A cysteine-null mutant FKBP12.6 retained redox-sensitive interaction with RyR2, suggesting that the effect of the redox reagents is exclusively via sites on the ryanodine receptor. Cysteine 2-10 FKBP prolyl isomerase 1B Homo sapiens 23-31 16908189-5 2007 However, refolding of the protein containing the longer tag in vitro results in reduced PPIase activity (the k(cat)/K(m) was reduced from 1 x 10(6)M(-1)s(-1) to 0.81 x 10(6)M(-1)s(-1)) and a 6-fold affinity loss for rapamycin.

Calcium 210-217 FKBP prolyl isomerase 1B Homo sapiens 155-165 15591045-7 2005 However, expression of a large RyR2 C-terminal construct in mammalian cells encompassing the pore-forming transmembrane domains exhibits rapamycin-sensitive binding specifically to FKBP12.6 but not to FKBP12. Sirolimus 137-146 FKBP prolyl isomerase 1B Homo sapiens 181-189 15709953-5 2005 These regulatory proteins include calstabin1/calstabin2 (FKBP12/FKBP12.6), a 12/12.6 kDa subunit that stabilizes the closed state of the channel and prevents aberrant calcium leak from the SR. Kinases and phosphatases are targeted to RyR2 channels and modulate RyR2 function in response to extracellular signals.
