SHH

Product Name: Human Sonic Hedgehog (SHH) recombinant protein carrier-free
Description: Sonic hedgehog homolog (SHH) is one of three proteins in the mammalian signaling pathway family called hedgehog, the others being desert hedgehog (DHH) and Indian hedgehog (IHH). SHH is the best studied ligand of the hedgehog signaling pathway. It plays a key role in regulating vertebrate organogenesis, such as in the growth of digits on limbs and organization of the brain. Sonic hedgehog is the best established example of a morphogen as defined by Lewis Wolpert's French flag model—a molecule that diffuses to form a concentration gradient and has different effects on the cells of the developing embryo depending on its concentration. SHH remains important in the adult. It controls cell division of adult stem cells and has been implicated in development of some cancers. Recombinant Sonic Hedgehog is an approximately 20 kDa protein expressed in E. coli consisting of 175 amino acid residues, including an N-terminal Ile-Ile sequence substituted for the naturally occurring chemically modified Cys residue.
