  • Function

    Transcription factor for tyrosinase and tyrosinase-related protein 1. Binds to a symmetrical DNA sequence (E-boxes) (5'-CACGTG-3') found in the tyrosinase promoter. Plays a critical role in the differentiation of various cell types as neural crest-derived melanocytes, mast cells, osteoclasts and optic cup-derived retinal pigment epithelium.
  • Tissue specificity

    Isoform M is exclusively expressed in melanocytes and melanoma cells. Isoform A and isoform H are widely expressed in many cell types including melanocytes and retinal pigment epithelium (RPE). Isoform C is expressed in many cell types including RPE but not in melanocyte-lineage cells.
  • Involvement in disease

    Defects in MITF are the cause of Waardenburg syndrome type 2A (WS2A) [MIM:193510]. It is a dominant inherited disorder characterized by sensorineural hearing loss and patches of depigmentation. The features show variable expression and penetrance.
    Defects in MITF are a cause of Waardenburg syndrome type 2 with ocular albinism (WS2-OA) [MIM:103470]. It is an ocular albinism with sensorineural deafness.
    Defects in MITF are the cause of Tietz syndrome (TIETZS) [MIM:103500]. It is an autosomal dominant disorder characterized by generalized hypopigmentation and profound, congenital, bilateral deafness. Penetrance is complete.
  • Sequence similarities

    Belongs to the MiT/TFE family.
    Contains 1 basic helix-loop-helix (bHLH) domain.
  • Post-translational

    Phosphorylation at Ser-405 significantly enhances the ability to bind the tyrosinase promoter.
  • Cellular localization

  • Immunohistochemical analysis of RPE (Retinal Pigment Epithelium) in chicken embryo (stage 14) labelling MiTF with ab122982 at dilution of 1/300. Embryo was fixed with paraformaldehyde and embedded in OCT compound and sectioned with a cryostat at 8
    μm. Alexa Fluor® 488 conjugated anti-rabbit IgG was used at the secondary antibody. 

    At stage 14, Mitif protein is detected throughout the RPE (Retinal Pigment Epithelium).

  • Immunofluorescence analysis of mouse primary melanocytes labelling MiTF with ab122982 at a dilution of 1/300 (right). Nuclei couterstained with DAPI (blue) (left).
