| Status | Available to order |
| EMMA ID | EM:06222 |
| International strain name | STOCK Pmeltm1.1Sson/Kctt |
| Alternative name | Pmel KO |
| Strain type | Targeted Mutant Strains : Knock-out |
| Allele/Transgene symbol | Pmeltm1.1Sson |
| Gene/Transgene symbol | Pmel |
Information from provider
| Provider | Susanne Kerje |
| Provider affiliation | IMBIM, Uppsala University |
| Genetic information | Exons 2 and 3 of the Pmel 17 gene have been knocked out resulting in a non functional protein. |
| Phenotypic information | Mice lacking PMEL have almost normal fur pigmentation. Loss of PMEL has a dramatic effect on the morphology of the melanosomes in skin, hair, and eye, such that the normally rod-shaped melanosomes in wild-type animals are spherical in the knockout mice. The knockout animals also have a substantial reduction in the content of black pigment in hair. |
| Breeding history | The Pmel KO is maintained in a C57BL/6 background. |
