CRASP-1, or Complement Regulator-Acquiring Surface Protein 1, is a multifunctional protein of Lyme disease-causing B. burgdorferi that binds to several human extracellular matrix proteins and plasminogen, including factor H (resulting in inhibition of complement activation in mammals) and Human Bone Morphogenic Protein 2. These interactions may contribute to adhesion, bacterial colonization, and organ tropism and may allow dissemination of B. burgdorferi in the host. B. burgdorferi spirochetes express up to 5 complement regulator-acquiring surface proteins. Multiple copies of sequences analagous to CRASP-1 genes have been detected in Borrelia plasmids. Borrelia species contain a large number of plasmids, of linear and circular, some of which appear to repeat sequences or contain fragments of other genes. These regions may serve as potentially usable information for the survival of Borrelia in its multiple environments during its life cycle. In addition, the sequence for CRASP-1 contains a repeated sequence folded into a stable stem loop structure typical of RNA genes. Lyme disease proteins are ideal for researchers interested in immunology, neurology, rheumatology, coinfections, autoimmune, and neurodegenerative diseases.

Target Details

CRASP1  - View All CRASP1 Products
Crasp1 is a fusion protein with an MBP tag and was expressed in E. coli. Analysis by SDS-PAGE resulted in a pattern consistent with purified Crasp1 and was estimated to be greater than 90% pure.

Application Details

Crasp1 is suitable as a control in immunological assays. Specific conditions for reactivity should be optimized by the end user. Expect bands at 69.3 kDa for CRASP-1-MBP, (26.9 kDa for CRASP-1 and 42.4 kDa for MBP) in size corresponding to Crasp1 by Western blotting in the appropriate cell lysate or extract. Complement Regulator-Acquiring Surface Protein 1 was tested in SDS-page and western blot.
