Identification and characterization of multiple isoforms of a murine and human tumor suppressor, patched, having distinct first exons.


Mutations in mouse and human patched (PTCH) genes are associated with birth defects and cancer. PTCH, a 12-pass transmembrane protein, is a receptor for Sonic hedgehog (Shh) signaling proteins. Shh proteins activate transcription of target genes, including PTCH, via GLI transcription factors. Here we identified seven and five isoforms of human and mouse… (More)
