Gene Description

MITF (microphthalmia-associated transcription factor) is a basic helix-loop-helix leucine-zipper (bHLH-LZ) transcription factor of the MiT/TFE family (with TFE3, TFEB and TFEC). It binds DNA as a homodimer or as a heterodimer with other MiT/TFE members, recognising E-box (CACGTG) and M-box (TCATGTG) elements, and predominantly activates RNA polymerase II transcription of target genes. In melanocytes and retinal pigment epithelium it is the master regulator of differentiation and pigmentation, directly activating the melanogenic genes TYR, TYRP1 and MC1R as well as genes for melanosome biogenesis and transport, survival and proliferation; it also acts in mast cell and osteoclast differentiation, and can repress some targets such as ZEB1. Alternative promoters generate isoforms with distinct N-termini (melanocyte-specific MITF-M; widely expressed MITF-A, -C, -H), which differ in target selectivity. MITF activity is controlled by signalling-dependent phosphorylation, sumoylation and ubiquitination: phosphorylation promotes 14-3-3-mediated cytoplasmic retention, and in nutrient-replete cells the N-terminally extended isoforms are recruited by Rag GTPases to the lysosomal surface and phosphorylated by mTORC1, promoting their degradation. Heterozygous MITF variants cause Waardenburg syndrome type 2A and Tietz albinism-deafness syndrome, biallelic dominant-negative combinations cause COMMAD syndrome, and the E318K variant predisposes to melanoma.

KEEP AS NON CORE
Summary: MITF knockdown/loss experiments in the ZEB2-MITF-ZEB1 network paper support MITF-dependent repression of target genes such as ZEB1.
Reason: The cached record is abstract-only, so the specific readout cannot be checked, but MITF-M occupancy of the ZEB1 locus with repression is independently documented (Reactome, CUT&RUN/ChIP-seq). Repression is a genuine but secondary activity of a factor whose primary output is activation; non-core. Deferring to the curator who read the full text.

Summary: MITF is a sequence-specific bHLH-LZ transcription factor that occupies chromatin at target loci (ChIP at FOS, BEST1; CUT&RUN/ChIP-seq at ZEB1).
Reason: Chromatin location is the expected consequence of sequence-specific binding at cis-regulatory elements, shown directly by ChIP in human cells.
Supporting Evidence:

Summary: PAINT root-node (PTN005248237) inference; MITF is itself a seed for this IBD. MITF binds M-box (TCATGTG) and E-box (CACGTG) elements in Pol II-transcribed target promoters.
Reason: Core molecular function. Sequence-specific binding to E-box/M-box elements is shown by EMSA for wild-type human MITF and by in vitro binding to the tyrosinase-family M box; the IBA reflects inheritance of this function from the MiT/TFE family root.

Summary: MITF is a DNA-binding transcription factor acting at RNA polymerase II promoters/enhancers (IBA).

It covers both the predominant activator activity (GO:0001228, accepted separately) and context-specific repression (e.g. ZEB1), so it is appropriately kept alongside the more specific activator term.

Summary: Ortholog-transferred chromatin binding.
Reason: MITF occupancy of chromatin at target loci is well documented (ChIP, CUT&RUN), and MITF recruits chromatin-remodelling partners (SWI/SNF per Reactome), so the claim is reasonable; however the informative activity is sequence-specific DNA binding, so this is kept as non-core.

KEEP AS NON CORE
Summary: A pool of MITF is retained in the cytoplasm, by phospho-dependent 14-3-3 binding and via mTORC1/Rag-regulated pathways, as an inactive regulated reservoir.
Reason: Cytoplasmic localization is real and well documented but reflects regulation of MITF (sequestration away from its site of action) rather than where it executes its function; non-core.

Summary: A pool of MITF is retained in the cytoplasm, by phospho-dependent 14-3-3 binding and via mTORC1/Rag-regulated pathways, as an inactive regulated reservoir.
Reason: Cytoplasmic localization is real and well documented but reflects regulation of MITF (sequestration away from its site of action) rather than where it executes its function; non-core.

Summary: In the presence of nutrients, N-terminally extended MITF isoforms (MITF-A) are recruited to the lysosomal surface by active Rag GTPases, where mTORC1 phosphorylates them.

Core Functions

Sequence-specific DNA-binding transcription activator: as a homo- or heterodimer (with TFE3/TFEB/TFEC), MITF binds E-box/M-box elements in RNA polymerase II cis-regulatory regions and activates transcription of target genes. Experimentally established for human MITF.

Suggested Questions for Experts

Q: MITF-A is recruited to lysosomes by Rag GTPases like TFEB/TFE3, yet PAINT propagates lysosome organization and autophagy regulation only to the TFEB/TFE3 clade. Does MITF (outside melanoma) contribute measurably to CLEAR-network lysosomal gene activation in vivo?

Q: Which MITF isoform-specific N-terminal features determine target selectivity (e.g. MITF-M but not MITF-A activating PRKCB)?

Suggested Experiments

Experiment: Isoform-specific CRISPR deletion of MITF-A exon 1 in TFEB/TFE3 double-knockout RPE cells, followed by RNA-seq and CUT&RUN after Torin-1 treatment, to test whether MITF-A occupies and activates CLEAR elements.

Hypothesis: MITF-A, but not MITF-M, contributes to nutrient-responsive lysosomal gene expression in non-melanocytic cells.
