Ptch1 Gene Summary [Mouse]
Enables cyclin binding activity; heparin binding activity; and patched binding activity. Involved in several processes, including cellular response to cholesterol; chordate embryonic development; and regulation of DNA-templated transcription. Acts upstream of or within several processes, including chordate embryonic development; epithelial tube morphogenesis; and limb morphogenesis. Located in cilium; midbody; and plasma membrane. Is expressed in several structures, including alimentary system; central nervous system; embryo mesenchyme; genitourinary system; and limb. Used to study basal cell carcinoma; medulloblastoma; and nevoid basal cell carcinoma syndrome. Human ortholog(s) of this gene implicated in carcinoma (multiple); holoprosencephaly (multiple); nevoid basal cell carcinoma syndrome (multiple); and stomach cancer. Orthologous to human PTCH1 (patched 1). [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 mouse Ptch1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
