Synthesis and physiological implications of melanic pigments
WEBFeb 25, 2019 · The quantity of synthesized melanin is adjusted through the melanocortin 1 receptor (MC1R), which is located at the level of melanocyte membrane. MC1R belongs to the sub-group of the class A receptors coupled with G protein.
Determination of Melanin Synthetic Pathways - PMC - National …
WEBNov 11, 2011 · The determination to produce eumelanin and/or pheomelanin is regulated physiologically, primarily by the melanocortin 1 receptor (MC1R) as modulated by its opposing ligands, melanocyte stimulating hormone (MSH) and agouti signaling protein (ASIP); this is discussed in more detail by Rees (2011).
