Primary Identifier | MGI:3512050 | Allele Type | Targeted |
Attribute String | Conditional ready, Null/knockout | Gene | Mc4r |
Transmission | Germline | Strain of Origin | 129S4/SvJae |
Is Recombinase | false | Is Wild Type | false |
molecularNote | A loxP flanked PGK-neomycin selection marker inserted in the 5' UTR created a null allele. Cre recombinase deletes the selection marker, restoring normal activity of the allele. Mice fail to respond to MC4R agonist MTII. This is a null allele that can be "reactivated" by cre recombinase. |
