== Function ==
 +
[https://www.uniprot.org/uniprot/SHH_MOUSE SHH_MOUSE] Binds to the patched (PTC) receptor, which functions in association with smoothened (SMO), to activate the transcription of target genes. In the absence of SHH, PTC represses the constitutive signaling activity of SMO. Also regulates another target, the gli oncogene. Intercellular signal essential for a variety of patterning events during development: signal produced by the notochord that induces ventral cell fate in the neural tube and somites, and the polarizing signal for patterning of the anterior-posterior axis of the developing limb bud. Displays both floor plate- and motor neuron-inducing activity. The threshold concentration of N-product required for motor neuron induction is 5-fold lower than that required for floor plate induction (By similarity).<ref>PMID:7736596</ref>

Within the past few years, members of the hedgehog (hh) family of secreted signalling proteins have emerged as the primary signals generated by certain embryonic patterning centres. In vertebrate embryos, for example, sonic hedgehog expression in the notochord appears to be responsible for the local and long-range induction of ventral cell types within the neural tube and somites (reviewed in refs 1, 2). Protein products encoded by hh family members are synthesized as precursors that undergo autoprocessing to generate an amino-terminal domain that appears to be responsible for both local and long-range signalling activities, and a carboxy-terminal domain that contains the autoprocessing activity. As part of an effort to understand how hh family members participate in cell-to-cell signalling, we have determined and report here the crystal structure at 1.7 A of the amino-terminal domain of murine Sonic hedgehog (Shh-N). The structure revealed a tetrahedrally coordinated zinc ion that appears to be structurally analogous to the zinc coordination sites of zinc hydrolases, such as thermolysin and carboxypeptidase A. This previously unsuspected catalytic site represents a distinct activity from the autoprocessing activity that resides in the carboxy-terminal domain.
