| Subcellular Location | SUBCELLULAR LOCATION: [Desert hedgehog protein A N-product]: Cell membrane {ECO:0000250}; Lipid-anchor {ECO:0000250}; Extracellular side {ECO:0000250}. Note=The N-terminal peptide remains associated with the cell surface. {ECO:0000250}.; SUBCELLULAR LOCATION: [Desert hedgehog protein A C-product]: Secreted, extracellular space {ECO:0000250}. Note=The C-terminal peptide diffuses from the cell. {ECO:0000250}. |
| Modified Residue | |
| Post Translational Modification | PTM: The C-terminal domain displays an autoproteolysis activity and a cholesterol transferase activity. 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-terminal fragment (N-product). This covalent modification appears to play an essential role in restricting the spatial distribution of the protein activity to the cell surface. The N-product is the active species in both local and long-range signaling, whereas the C-product has no signaling activity (By similarity). {ECO:0000250}. |
