Spontaneous Allele Detail
Symbol: Mc1rE-tob
Name: melanocortin 1 receptor; tobacco darkening
MGI ID: MGI:1856030
Synonyms: Etob
Gene: Mc1r  Location: Chr8:124133846-124137483 bp, + strand  Genetic Position: Chr8, 72.1 cM
Strain of Origin:  M. m. domesticus poschiavinus
Allele Type:    Spontaneous
Mutation:    Single point mutation
Mutation detailsTwo independent PCR assays found a C-to-T mutation at coding nucleotide 206 resulting in a serine to leucine alteration in codon 69 (p.S69L). A second nucleotide C-to-T change results in a silent mutation at position 166. The result is a receptor that is overactive, though responsive to hormone regulation, and produces a greater activation of the MC1R effector, G protein-coupled adenylyl cyclase, than does the wild-type allele. (J:4636)
Inheritance:    Semidominant
