Research using MT-1 in cell systems expressing MC1R variants associated with red hair and fair skin has characterised reduced cAMP signalling responses, impaired MITF activation, and decreased melanogenesis , documenting the functional consequences of loss-of-function MC1R polymorphisms at the receptor signalling level and establishing the molecular basis for the reduced photoprotective melanogenesis capacity associated with these variants
Lyophilized powder contains the peptide in a dried, stable form
Crotonobetaine, to our knowledge, has not been measured in the brain, while peripheral crotonobetaine levels have been associated with an increased risk of cardiovascular events as well as increased fasting insulin levels (Koeth et al., 2014
