Specifications

Our Abpromise guarantee covers the use of ab85840 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

  • Biological activitySpecific activity is > 300 nmoles/min/mg, and is defined as the amount of enzyme that cleaves 1 µmole of suc-AAFP-pNA per minute at 25°C in Tris-Hcl pH 8.0 using chymotrypsin.

    Activity Assay

    1. Prepare 170 µl assay buffer into a suitable container and pre-chill on ice before use: The final concentrations are 200 mM Tris-Hcl, pH 8.0, and 20nM chymotrypsin.
    2. Add 10ul of recombinant FKBP1a/FKBP12 protein with 1 µg in assay buffer.
    3. Mix by inversion and equilibrate to 1°C and monitor the A405nm until the value is constant using a spectrophotometer.
    4. Add 20 µl pre-chilled 5mM suc-AAFP-pNA. (Substrate was dissolved in TFE that contained 460mM LiCl to a concentration of 3 mM)
    5. Record the increase in A405 nm for 30 minutes at 25°C.

  • FunctionMay play a role in modulation of ryanodine receptor isoform-1 (RYR-1), a component of the calcium release channel of skeletal muscle sarcoplasmic reticulum. There are four molecules of FKBP12 per skeletal muscle RYR. PPIases accelerate the folding of proteins. It catalyzes the cis-trans isomerization of proline imidic peptide bonds in oligopeptides.
  • Sequence similaritiesBelongs to the FKBP-type PPIase family. FKBP1 subfamily.
    Contains 1 PPIase FKBP-type domain.
  • Cellular localizationCytoplasm.
  • Information by UniProt
