  • Function

    Ubiquitin-like modifier that plays a role in intracellular transport of GABA(A) receptors and its interaction with the cytoskeleton. Involved in apoptosis. Involved in autophagy. Whereas LC3s are involved in elongation of the phagophore membrane, the GABARAP/GATE-16 subfamily is essential for a later stage in autophagosome maturation.
  • Tissue specificity

    Heart, brain, placenta, liver, skeletal muscle, kidney and pancreas.
  • Sequence similarities

    Belongs to the ATG8 family.
  • Post-translational

    The precursor molecule is cleaved by ATG4B to form the cytosolic form, GABARAP-I. This is activated by APG7L/ATG7, transferred to ATG3 and conjugated to phospholipid to form the membrane-bound form, GABARAP-II.
  • Cellular localization

    Endomembrane system. Cytoplasm, cytoskeleton. Golgi apparatus membrane. Cytoplasmic vesicle, autophagosome. Largely associated with intracellular membrane structures including the Golgi apparatus and postsynaptic cisternae. Colocalizes with microtubules (By similarity). Localizes also to discrete punctae along the ciliary axoneme (By similarity).

Thank you very much for your interest in our antibodies.

According to a quick blast check the immunogen of ab1398 has a homology with Drosophila melanogaster of 82%. We generally expect cross reaction of an antibody from 85% homology and more.

I checked our other Anti-GABARAP antibodies and would like to recommend ab109364 (https://www.abcam.com/index.html?datasheet=109364 (or use the following: https://www.abcam.com/index.html?datasheet=109364).). The immunogen shows 92% homology with Drosophila melanogaster and therefore it is likely to cross react.

To our knowledge, ab109364 has not been experimentally tested in Drosophila melanogaster. Therefore, I can offer a discount off a future purchase if you buy ab109364 now, test it in Drosophila melanogaster and submit feedback to us in the form of an Abreview. It doesn’t matter whether the Abreview is positive or negative, we would just really like to receive your feedback. The discount would be to the value of ab109364 off a future order.

If you are interested in this offer, please follow these steps:

1. Reply to this e-mail to let me know that you would like to proceed and test ab109364 in Drosophila melanogaster. I will then send a discount code. This code must be issued before purchasing ab109364 so please wait for my reply before ordering.

2. Purchase ab109364 either by phone, fax, or online (www.abcam.com).

3. Test it in Drosophila melanogaster.

4. Let us know the results, positive or negative, using our Abreview system (this will take about 10 minutes and images are great if you have them!). To find out how to submit an Abreview, please visit: https://www.abcam.com/abreviews.

5. After the review is submitted to us, the discount code becomes active. Simply place your new order by phone, fax, or on the web and mention the discount code. The discount can be redeemed for anyproduct ordered and the discount code is valid for 4 months after issue.
Please remember that submission of the Abreview is sufficient for the discount code to become active.

We are always pleased to obtain feedback about our products and any information is greatly appreciated! Even if ab109364 turns out to be unsuitable for Drosophila melanogaster, you will still receive the discount on your next purchase after your Abreview has been submitted.

Please let me know if you have any questions about this offer and I would be happy to help you further.

The Terms and Conditions of this offer can be found at: www.abcam.com/collaborationdiscount.
