Lineage: Eukaryota; Metazoa; Ecdysozoa; Arthropoda; Hexapoda; Insecta; Pterygota; Neoptera; Endopterygota; Diptera; Brachycera; Muscomorpha; Ephydroidea; Drosophilidae; Drosophila; Sophophora
Also known as: CG9211; CT26314; Dmel\CG9211; iHog; Ihog; IHOG
Summary: Enables several functions, including coreceptor activity; hedgehog family protein binding activity; and heparin binding activity. Involved in several processes, including maintenance of protein location in extracellular region; regionalization; and smoothened signaling pathway. Located in cell surface; cytoneme; and plasma membrane. Is expressed in several structures, including dorsal epidermis primordium; embryonic anal pad; embryonic dorsal epidermis; embryonic epipharynx; and imaginal disc. Human ortholog(s) of this gene implicated in holoprosencephaly 11. Orthologous to human BOC (BOC cell adhesion associated, oncogene regulated) and CDON (cell adhesion associated, oncogene regulated).

These results, thus, not only reveal a mechanism for Ihog-mediated cell-cell interactions but also suggest a direct Hh-mediated regulation of both intracellular signaling and cell adhesion through Ihog.

Patched and Ihog activity are mutually required for receptor endocytosis and degradation, triggered by Hedgehog protein binding, and causing reduced levels of Ihog/Boi proteins in a stripe of cells at the anterior/posterior compartment boundary of the wing imaginal disc.

Hh and its co-receptor Ihog are in exovesicles transported via cytonemes. Hh transport via exosomes along cytonemes is a significant mechanism for the restricted distribution of a lipid-modified morphogen.
