| Post Translational Modifications | When nutrients are present, phosphorylation by MTOR at Ser-5 via non-canonical mTORC1 pathway promotes ubiquitination by the SCF(BTRC) complex, followed by degradation. Phosphorylation at Ser-405 significantly enhances the ability to bind the tyrosinase promoter. Phosphorylation by MARK3/cTAK1 at Ser-280 promotes association with 14-3-3/YWHA adapters and retention in the cytosol. Phosphorylated at Ser-180 and Ser-516 following KIT signaling, triggering a short live activation: Phosphorylation at Ser-180 and Ser-516 by MAPK and RPS6KA1, respectively, activate the transcription factor activity but also promote ubiquitination and subsequent degradation by the proteasome. Phosphorylated in response to blue light (415nm). Ubiquitinated by the SCF(BTRC) and SCF(FBXW11) complexes following phosphorylation ar Ser-5 by MTOR, leading to its degradation by the proteasome. Ubiquitinated following phosphorylation at Ser-180, leading to subsequent degradation by the proteasome. Deubiquitinated by USP13, preventing its degradation. |
| Function | Transcription factor that acts as a master regulator of melanocyte survival and differentiation as well as melanosome biogenesis. Binds to M-boxes (5'-TCATGTG-3') and symmetrical DNA sequences (E-boxes) (5'-CACGTG-3') found in the promoter of pigmentation genes, such as tyrosinase (TYR). Involved in the cellular response to amino acid availability by acting downstream of MTOR: in the presence of nutrients, MITF phosphorylation by MTOR promotes its inactivation. Upon starvation or lysosomal stress, inhibition of MTOR induces MITF dephosphorylation, resulting in transcription factor activity. Plays an important role in melanocyte development by regulating the expression of tyrosinase (TYR) and tyrosinase-related protein 1 (TYRP1). Plays a critical role in the differentiation of various cell types, such as neural crest-derived melanocytes, mast cells, osteoclasts and optic cup-derived retinal pigment epithelium. |
