Synthetic peptide corresponding to residues surrounding Glu53 of human Shh. Species Sequence Homology: mouse, Xenopus
Hedgehog proteins (Hh) are secreted signaling proteins that play many roles during animal development. Aberrant Hh signaling activity can be associated with numerous birth defects and uncontrolled Hh pathway activation is linked to the development of several types of cancers (1-2). The three identified vertebrate Hh genes are Sonic (Shh), Indian (Ihh) and Desert (Dhh), all of which have distinct as well as overlapping roles (3-5). Hh proteins are synthesized as 45kD precursors that undergo auto-cleavage to generate a 19kD amino-terminal peptide (Hh-N) and a carboxy-terminal peptide (Hh-C). The amino-terminal peptide becomes covalently attached to a cholesterol molecule at its carboxy terminus and acetylated at its amino terminus. This doubly modified Hh-N peptide is released from cells and responsible for all known Hedgehog signaling activity (6). Applications: Suitable for use in Western Blot. Other applications not tested. Recommended Dilution: Western Blot: 1:1000 Optimal dilutions to be determined by the researcher. Storage and Stability: May be stored at 4C for short-term only.
