  • 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.

  • ab3201 staining MiTF in the SK-MEL-28 (a human melanoma cell line) by ICC/IF(Immunocytochemistry/immunofluorescence). Cells were fixed with Paraformaldehyde and permeabilized with Triton X-100 0.5% in PBS. Samples were incubated with primary antibody (1/100) for 24 hours at 4°C. An Alexa Fluor®488-conjugated Goat anti-mouse IgG polyclonal(1/1000) was used as the secondary antibody. SK-MEL-28 cells was grown on chamber slide. MiTF was found to strictly localised in the nucleus. Cells were counter-stained with DAPI.

  • ICC/IF image of ab3201 stained Malme-3M cells. The cells were 4% formaldehyde fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody ab3201 at 5µg/ml overnight at +4°C. The secondary antibody (pseudo-colored green) was Alexa Fluor® 488 goat anti- mouse (ab150117) IgG (H+L) preadsorbed, used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (pseudo-colored red) at a 1/200 dilution for 1h at room temperature. DAPI was used to stain the cell nuclei (pseudo-colored blue) at a concentration of 1.43µM for 1hour at room temperature.

The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab3201, 1µg/1x106 cells) for 30 min at 22ºC. The secondary antibody used was DyLight® 488 goat anti-mouse IgG (H+L) (ab96879) at 1/500 dilution for 30 min at 22ºC. Isotype control antibody (black line) was mouse IgG1 [ICIGG1] (ab91353, 2µg/1x106 cells ) used under the same conditions. Acquisition of >5,000 events was performed.

Thank you for your enquiry.

I would be pleased to help answer your questions. I assume you are using the western blot application?

Regarding dilution to use the antibody in WB, the details on the online datasheet for ab79475 recommend tousethe antibody at aconcentration of 0.5 - 1 ug/ml. For ab3201, the image on the datasheet includes information that this has been used at 5 ug/ml. Please note that these concentrations area guideline only and may require some individual optimization.

The incubation time and temperature will also require some individual optimization. I would recommend to try 4oC overnight. This can often provide the most efficient and specific staining.

I hope this will be helpful to you. If you have any further questions, please do not hesitate to contact us.

Thank you for contacting Abcam yesterday.

I am working with our lab to try and understand where the data stating there was a lack of reactivity with mouse came from, as we have not tested it on mouse. I do apologize for the confusion and for bringing this to our attention. Once we have looked into this more thoroughly, we will update the datasheet as necessary.

If there is anything else I can help you with, please let me know.

Thank you for your reply.

I can confirm that this antibody has been tested successfully in WB with blocking in 5% nonfat dry milk with PBS + 0.1%Tween 20. However, please note this may require some individual optimization.

If you have any further questions, please do not hesitate to contact us.

Thank you for your email. I'm happy to hear that the new batch is working for your. I was able to obtain an image of human melanoma stained with ab3201 which I'm sending you as a separate email. Please let me know if you have any additional questions.

Thank you for your email. I unfortunately cannot send you a positive control free of charge. 501 Mel cells and Melanoma are recommended as positive controls for ab3201. If you have any additional questions, please let us know.

Thank you for your email. I contacted the originator of this antibody concerning the problem that you were experiencing. It turns out that there is a problem with that particular batch and so I'm sending you a vial from a new batch free of charge. This is on order# 79431 and will take approximately 1 week for you to receive it as we have to first receive it from the originator. You will receive email updates regarding shipping. Also, you previously contacted me back in March because the vial that you received was labeled [C5] instead of [D5]. I had thought that there was a mis-labeling problem but the clone number was changed from [C5] to [D5] this past September. If you have any additional questions, please do not hesitate to contact us again.

Thank you for contacting us and providing more details of your protocol. We are very sorry to hear that you are having problem with this antibody. We have retested this antibody and would like to make the following suggestions: 1. For formalin-fixed sections, try to incubate the samples wit this primary antibody at 4-8 ug/ml concentration for 30 min at room temperature. 2. Staining of formalin-fixed tissue requires boiling tissue sections in 10 mM citrate buffer (pH 6.0) for 10-20 min followed by cooling at RT for 20 min. 3. Use recommended positive control - human melanoma. We hope this will help. Should you still need further assistance, then please do not hesitate to contact us again.
