Sonic Hedgehog/SHH (C-6His) (recombinant mouse)

Protein Construction: Recombinant Mouse Sonic Hedgehog is produced by our Mammalian expression system and the target gene encoding Cys25­Gly198 is expressed with a 6His tag at the C-terminus. Sequence: Cys25­-Gly198. Fusion tag: C-6His Endotoxin: < 1.0 EU per µg as determined by the LAL method. Apparent Molecular Mass: 22 kDa. Protein function: Mouse Sonic Hedgehog Homolog (SHH) belongs to a three-protein family called Hedgehog. The other two family members are Indian Hedgehog (IHH) and Desert Hedgehog (DHH). Hedgehog proteins are key signaling molecules in embryonic development. SHH is expressed in various embryonic tissues and plays critical roles in regulating the patterning of many systems, such as limbs and brain. SHH also plays an important role in adult, including the division of adult stem cells and the development of certain cancers and other diseases.Mouse Shh is synthesized as a 437 aa precursor that contains a 24 aa signal sequence and a 413 aa mature region. The mature region is autocatalytically processed into a nonglycosylated, 20 kDa, 174 aa N­terminal fragment (Shh­N), and a catalytic­processing,glycosylated, 34 kDa, 239 aa C­terminal fragment. The 20 kDa Shh­N fragment is the core of the active hedgehog molecule. Mouse Shh­N is 99%, 98%, and 100% aa identical to human, rat and gerbil Shh­N, respectively. Protein function: [Sonic hedgehog protein]: The C-terminal part of the sonic hedgehog protein precursor displays an autoproteolysis and a cholesterol transferase activity (PubMed:8824192, PubMed:7891723). Both activities result in the cleavage of the full-length protein into two parts (ShhN and ShhC) followed by the covalent attachment of a cholesterol moiety to the C-terminal of the newly generated ShhN (PubMed:8824192). Both activities occur in the reticulum endoplasmic (PubMed:21357747). Once cleaved, ShhC is degraded in the endoplasmic reticulum (PubMed:21357747). [The UniProt Consortium]
