General info

Function

Plays a role in embryonic morphogenesis; it is involved in the regulation of endochondral skeleton formation, and the development of retinal pigment epithelium (RPE), photoreceptors and periocular tissues (By similarity).. Indian hedgehog protein. The C-terminal part of the indian hedgehog protein precursor displays an autoproteolysis and a cholesterol transferase activity (By similarity). Both activities result in the cleavage of the full-length protein into two parts followed by the covalent attachment of a cholesterol moiety to the C-terminal of the newly generated N-product (By similarity). Both activities occur in the endoplasmic reticulum (By similarity). Plays a role in hedgehog paracrine signaling (PubMed : 24342078). Associated with the very-low-density lipoprotein (VLDL) particles to function as a circulating morphogen for endothelial cell integrity maintenance (PubMed : 20839884).. Indian hedgehog protein N-product. The dually lipidated indian hedgehog protein N-product is a morphogen which is essential for a variety of patterning events during development. Binds to the patched (PTCH1) receptor, which functions in association with smoothened (SMO), to activate the transcription of target genes (By similarity). Plays a role in morphogenesis of the skeleton by coordinating growth and differentiation of the endochondral skeleton (By similarity). Positively regulates PTHLH expression during endochondral bone formation preventing chondrocyte hypertrophy. In contrast, participates in normal chondrocyte proliferation in a PTHLH-independent pathway (By similarity).

Sequence similarities

Belongs to the hedgehog family.

Post-translational modifications

Indian hedgehog protein N-product. Cholesterylation is required for N-product targeting to lipid rafts and multimerization.. Indian hedgehog protein. The C-terminal domain displays an autoproteolysis activity and a cholesterol transferase activity (By similarity). Both activities result in the cleavage of the full-length protein and covalent attachment of a cholesterol moiety to the C-terminal of the newly generated N-product (By similarity). The N-product is the active species in both local and long-range signaling, whereas the C-product is degraded in the endoplasmic reticulum (By similarity).. Indian hedgehog protein N-product. N-palmitoylation by HHAT of N-product is required for indian hedgehog protein N-product multimerization and full activity.
