SOX10 and PAX3 bind directly to cognate elements in the proximal MITF-M promoter to synergistically stimulate its transcription (Zhang et al, 2012; Potterf et al, 2000; Bondurand et al, 2000; Watanabe et al, 1998; reviewed in Mort, 2015; White and Ton, 2008; Goding and Arnheiter, 2019).
PAX3 is a DNA-binding transcription factor with roles in neural development and myogenesis that is expressed in the neural tube prior to neural crest migration (reviewed in Monsoro-Burq, 2015). PAX3 contains a homeobox domain and a paired domain that bind to consensus sequences ATTAAT and GGAAC, respectively (Chalepakis et al, 1994a,b). Consensus binding sites for PAX3 containing these elements have been identified in the promoter of the MITF gene (Watanabe et al, 1998; reviewed in Goding and Arnheiter, 2019).
SOX10 is a member of the sex-determining factor (SRY)-like, high mobility group family of transcription factors that are involved in cell lineage pathways (Schock and LaBonne, 2020). SOX10 is expressed in early migrating neural crest cells, some of which go on to develop into melanoblasts and melanocytes (Herbarth et al 1998; Pusch et al 1998; reviewed in Mort et al, 2015; White and Zon, 2008). SOX10 binding sites have been identified in the proximal and distal regions of the MITF promoter. These sites stimulate expression of reporter genes in vitro, are bound by SOX10 as assessed by electrophoretic mobility shift assays, and drive in vivo expression in mice (Bondurand et al, 2000; Potterf et al, 2000; Zhang et al, 2012; reviewed in Goding and Arnheiter, 2019).
SOX10 transcription factor activity is regulated by SUMOylation, and SOX10 has been shown to be sumoylated at lysine 55 in a UBE2I (also known as UBC9)-dependent manner (Girard et al, 2006; Taylor and La Bonne, 2005; Han et al, 2018). MAPK1-dependent phosphorylation of SOX10 at residues T240 and T244 interferes with the interaction of SOX10 with UBE2I and inhibits SOX10 transcription factor activity at the MITF promoter (Han et al, 2018). A direct transcriptional activation role for SOX10 K55 sumoylation at the MITF promoter has not been shown, however.
