Gene Information

human ... PTCH1(5727)

General description

Protein patched homolog 1 (PTCH1) is the receptor for secreted sonic hedgehog ligand and belongs to the patched gene family. It is mapped to human chromosome 9q22.32. Ptch1 has 12 transmembrane regions, intracellular middle-loop domain (MLD) and C-terminal domain (CTD) essential for oligomerization.

Immunogen

Synthetic peptide directed towards the C terminal region of human PTCH1

Application

Anti-PTCH1 antibody produced in rabbit has been used in Flow cytometry/Cell sorting. It is suitable for western blotting at a concentration of 0.25μg/ml and for immunohistochemistry of paraffin-embedded tissue sections at a concentration of 4-8μg/ml.
Applications in which this antibody has been used successfully, and the associated peer-reviewed papers, are given below.

Biochem/physiol Actions

Mutations in protein patched homolog 1(PTCH1) is implicated in autosomal dominant disorder called the Gorlin syndrome, resulting in developmental abnormalities.
PTCH1 (patched 1; PTC) activates the sonic hedgehog (Hh) signaling pathway that is involved in the development of embryonic structures. PTCH1 is a tumor suppressor that maintains the activity of GLI1, the downstream target of Hh signaling. Mutations and methylation status in PTCH1 gene result in tumorigenesis and malignancy in cancers including colorectal, gastric, melanoma and osteosarcoma.

Purified antibody supplied in 1x PBS buffer with 0.09% (w/v) sodium azide and 2% sucrose.

Hedgehog (Hh) signaling is largely suppressed in the normal differentiated tissues of the adult but activated in many cancers. The Hh pathway can either be activated by the expression of Hh ligands, or by mutations that cause constitutive, ligand-independent signaling.
