The specific activation/degradation signals derive from mapk/erk targeting of serine 73the results suggested that s1p reduced melanin synthesis via s1p(3) receptor-mediated erk and rsk-1 activation, and subsequent mitf dual phosphorylation and degradation. |

More interestingly, ERK-dependent phosphorylation of MITF at Ser 73 is essential for MITF ubiquitinilation and degradation (87). Putting together all these findings, it can be proposed that MAPK activation inhibits melanogenesis due to an increased MITF degradation which is dependent on the MAPK-induced MITF phosphorylation and ubiquitinilation. In summary, although the phosphorylation of MITF at Ser73 increases its intrinsic transcriptional activity, this phosphorylation also targets MITF to the proteasome for its degradation. Consequently, the decrease in MITF levels leads to a down-regulation of melanogenic enzymes expression and to an inhibition of melanogenesis. |

More interestingly, ERK-dependent phosphorylation of MITF at Ser 73 is essential for MITF ubiquitinilation and degradation (87). Putting together all these findings, it can be proposed that MAPK activation inhibits melanogenesis due to an increased MITF degradation which is dependent on the MAPK-induced MITF phosphorylation and ubiquitinilation. In summary, although the phosphorylation of MITF at Ser73 increases its intrinsic transcriptional activity, this phosphorylation also targets MITF to the proteasome for its degradation. Consequently, the decrease in MITF levels leads to a down-regulation of melanogenic enzymes expression and to an inhibition of melanogenesis. |
