Background

Function：Transcription factor that acts as a master regulator of melanocyte survival and differentiation as well as melanosome biogenesis (PubMed:10587587, PubMed:22647378, PubMed:27889061, PubMed:9647758). 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) (PubMed:10587587, PubMed:22647378, PubMed:27889061, PubMed:9647758). 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 (PubMed:36608670). Upon starvation or lysosomal stress, inhibition of MTOR induces MITF dephosphorylation, resulting in transcription factor activity (PubMed:36608670). Plays an important role in melanocyte development by regulating the expression of tyrosinase (TYR) and tyrosinase-related protein 1 (TYRP1) (PubMed:10587587, PubMed:22647378, PubMed:27889061, PubMed:9647758). 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 (PubMed:10587587, PubMed:22647378, PubMed:27889061, PubMed:9647758)

Isoforms & Post-Translational Modification：O75030 has 12 isomers: O75030-1: 58795 Da (predicted); O75030-2: 58163 Da (predicted); O75030-3: 56038 Da (predicted); O75030-4: 55405 Da (predicted); O75030-5: 58664 Da (predicted); O75030-6: 58031 Da (predicted); O75030-7: 57045 Da (predicted); O75030-8: 56412 Da (predicted); O75030-9: 46938 Da (predicted); O75030-10: 46305 Da (predicted); O75030-11: 40365 Da (predicted); O75030-12: 52527 Da (predicted).
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 (PubMed:36608670). Phosphorylation at Ser-405 significantly enhances the ability to bind the tyrosinase promoter (PubMed:10587587). Phosphorylation by MARK3/cTAK1 at Ser-280 promotes association with 14-3-3/YWHA adapters and retention in the cytosol (PubMed:16822840). 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 (PubMed:10673502). Phosphorylated in response to blue light (415nm) (PubMed:28842328);Ubiquitinated by the SCF(BTRC) and SCF(FBXW11) complexes following phosphorylation ar Ser-5 by MTOR, leading to its degradation by the proteasome (PubMed:36608670). Ubiquitinated following phosphorylation at Ser-180, leading to subsequent degradation by the proteasome (PubMed:10673502). Deubiquitinated by USP13, preventing its degradation (PubMed:10673502)

Subunit：Homodimer or heterodimer; dimerization is mediated via the coiled coil region (PubMed:24631970). Efficient DNA binding requires dimerization with another bHLH protein (PubMed:14975237). Binds DNA in the form of homodimer or heterodimer with either TFE3, TFEB or TFEC (PubMed:15507434). Interacts with small GTPases Rag (RagA/RRAGA, RagB/RRAGB, RagC/RRAGC and/or RagD/RRAGD); promoting its recruitment to lysosomal membrane in the presence of nutrients (PubMed:23401004, PubMed:36608670). Interacts with KARS1 (PubMed:14975237). Identified in a complex with HINT1 and CTNNB1 (PubMed:22647378). Interacts with VSX2 (By similarity)
