Ihh Gene Summary [Rat]
Predicted to enable calcium ion binding activity; patched binding activity; and very-low-density lipoprotein particle binding activity. Involved in several processes, including liver regeneration; maternal process involved in female pregnancy; and response to estradiol. Predicted to be located in extracellular matrix; extracellular region; and plasma membrane. Predicted to be active in extracellular space. Biomarker of osteoarthritis. Human ortholog(s) of this gene implicated in acrocapitofemoral dysplasia; brachydactyly type A1; retinopathy of prematurity; and syndactyly type 1. Orthologous to human IHH (Indian hedgehog signaling molecule). [provided by Alliance of Genome Resources, Jul 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Ihh often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
