  • Function

    ATP-dependent protease which is essential for axonal development.
  • Tissue specificity

    Ubiquitous. Highly expressed in the cerebellar Purkinje cells.
  • Involvement in disease

    Defects in AFG3L2 are the cause of spinocerebellar ataxia type 28 (SCA28) [MIM:610246]. It is a clinically and genetically heterogeneous group of cerebellar disorders. Patients show progressive incoordination of gait and often poor coordination of hands, speech and eye movements, due to degeneration of the cerebellum with variable involvement of the brainstem and spinal cord. SCA28 is an autosomal dominant cerebellar ataxia (ADCA) with a slow progressive course and no evidence of sensory involvement or cognitive impairment.
    Defects in AFG3L2 are the cause of spastic ataxia autosomal recessive type 5 (SPAX5) [MIM:614487]. A neurodegenerative disorder characterized by early onset spasticity, peripheral neuropathy, ptosis, oculomotor apraxia, dystonia, cerebellar atrophy, and progressive myoclonic epilepsy.
  • Sequence similarities

    In the N-terminal section; belongs to the AAA ATPase family.
    In the C-terminal section; belongs to the peptidase M41 family.
  • Cellular localization

    Mitochondrion membrane.

  • ICC/IF image of ab68023 stained HepG2 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 (ab68023, 5µg/ml) overnight at +4°C. The secondary antibody (green) was ab96879, DyLight® 488 goat anti-mouse IgG (H+L) used at a 1/250 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.

Thanks for submitting your completed questionnaire.

I am sorry this vial of ab68023 is giving you trouble. The protocol seems fine and the loading control staining worked well. So it seems there is an issue with the vial of antibody you received. If you have received this antibody within the past 6 months I am happy to offer a replacement, credit or refund.

In your reply, please include the Abcam order referenc number or PO number associated with this purchase so I can process your request.

Thank you for your response and yoru comment.

This is to let you know that I have just contacted and asked our Account Department to raise a credit note for you - for the cost of one vial of ab68023. For your information, the internal reference note for this credit is CN19981. You can use this credit in the near future for any of the products which are in the catalogue.

I hope this helps and if I can assist further, please do not hesitate to contact me.

Thank you for your response.

The datasheet suggests using AFG3L2 transfected 293T cell lysate as positive. Furthermore, the Western blot image describes that AFG3L2 transfected 293T cell lysate gave a signal at the expected size (around 80 kDa) whilst the non transfected 293T cell lysate did not give any signal.

I hope this helps and if I can assist further, please do not hesitate to contact me.

Thank you for your asking and letting us know the enquiry regarding ab68023 .

The antibody has been tested in AFG3L2 transfected 293T cell lysate as the datasheet indicates. We have no data/experience yet in using the antibody on other samples and it has not been tested on endogenously expressed samples.

I hope this helps and if I can assist further, please do not hesitate to contact me.

Thank you for your enquiry regarding ab68023 and for taking the time to provide some useful details of the experiments. I am very sorry to hear that you are having problems with this antibody.

Could you please confirm if the customer is using transfected 293T cells? This antibody has been tested on AFG3L2 transfected 293T cell lysate. The non-transfected cells do not have any signal for AFG3L2 (please see the Western blot image on the datasheet).

I look forward to hearing from you soon.
