Model Description: A Myc-IRES-Cre expression cassette was knocked into the Trpv1 gene stop codon site. Trpv1 is known as transient receptor potential cation channel, subfamily V, member 1. When crossed with a strain carrying a gene flanked by loxP sites, the flanked gene will be removed in cells expressing cre. This strain may be useful for studying the pain caused by heat and capsaicin.
