Molecular Weight
Approximately 19.9 kDa, a single non-glycosylated polypeptide chain containing 177 amino acids.
Formulation
Lyophilized from a 0.2 μm filtered concentrated solution in 10mM PB, pH 6.0, 300mM NaCl.
Reconstitution
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1 % BSA to a concentration of 0.1-1.0 mg/ml. Stock solutions should be apportioned into working aliquots and stored at ≤ -20 C. Further dilutions should be made in appropriate buffered solutions.
Background
Desert Hedgehog (Dhh) belongs to the highly conserved Hedgehog family of proteins which are involved in multiple developmental processes. Desert Hedgehog is a secreted, 45 kDa, 373 amino acid protein that undergoes autocatalytic cleavage between Gly198 and Cys199 catalyzed by the C-terminal domain, which releases the N-terminal domain with a concominant attachment of cholesterol at its new C-terminus. Dhh binds both Patched and Patched 2 as well as Hedgehog interacting protein (Hip). Within the N-terminal domain, human Dhh shares 97% aa sequence identity with mouse and rat Dhh. It shares approximately 75% aa seqeuence identity with human Indian (Ihh) and Sonic Hedgehog (Shh). Dhh is expressed in the female by ovarian granulosa cells and the corporus luteum. Its upregulation in ovarian cancer correlates positively with proliferative index, and negatively with prognosis. Dhh is also expressed by Schwann cells and is upregulated following nerve injury.
