IHC (Immunohistochemisry)
(At 1/200 staining Human lung cancer tissue sections by IHC-P. The tissue was formaldehyde fixed and a heat mediated antigen retrieval step in citrate buffer was performed. The tissue was then blocked and incubated with the antibody for 1.5 hours at 22 degree C. An HRP conjugated goat anti-rabbit antibody was used as the secondary antibody.)

Conjugation
Unconjugated
Fragment
Fab fragment
Post Translational Modifications
Monoubiquitinated N-terminally by UBE2W, possibly leading to activate the deubiquitinating enzyme activity.
Subunit Structure
Interacts with STUB1/CHIP (when monoubiquitinated) (By similarity). Interacts with DNA repair proteins RAD23A and RAD23B. Interacts with BECN1 (via its poly-Gln domain). Interacts with PRKN, UBR2, VCP and tubulin. Short isoform 1 interacts with CASP7.
Similarity
The UIM domains bind ubiquitin and interact with various E3 ubiquitin-protein ligase, such as STUB1/CHIP. They are essential to limit the length of ubiquitin chains (By similarity).The poly-Gln domain is involved in the interaction with BECN1 and subsequent starvation-induced autophagy (PubMed:28445460).
Subcellular Location
Nucleus matrix. Nucleus.
Note: Predominantly nuclear, but not exclusively, inner nuclear matrix.

Related Product Information for anti-ATXN3 antibody
Deubiquitinating enzyme involved in protein homeostasis maintenance, transcription, cytoskeleton regulation, myogenesis and degradation of misfolded chaperone substrates. Binds long polyubiquitin chains and trims them, while it has weak or no activity against chains of 4 or less ubiquitins. Involved in degradation of misfolded chaperone substrates via its interaction with STUB1/CHIP: recruited to monoubiquitinated STUB1/CHIP, and restricts the length of ubiquitin chain attached to STUB1/CHIP substrates and preventing further chain extension (By similarity). Interacts with key regulators of transcription and represses transcription: acts as a histone-binding protein that regulates transcription. Regulates autophagy via the deubiquitination of 'Lys-402' of BECN1 leading to the stabilization of BECN1.

Product Notes
The ATXN3 atxn3 (Catalog #AAA329787) is an Antibody produced from Rabbit and is intended for research purposes only. The product is available for immediate purchase. The Phospho-Ataxin 3 (Ser256) Antibody reacts with Human, Mouse, Rat Predicted Reactivity: Pig (100%), Zebrafish (86%), Bovine (100%), Horse (100%), Sheep (100%), Rabbit (100%), Dog (100%), Chicken (100%), Xenopus (100%) and may cross-react with other species as described in the data sheet. AAA Biotech's Ataxin 3 can be used in a range of immunoassay formats including, but not limited to, ELISA (Peptide ELISA), IHC (Immunohistochemistry), WB (Western Blot). Researchers should empirically determine the suitability of the ATXN3 atxn3 for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. It is sometimes possible for the material contained within the vial of "Ataxin 3, Polyclonal Antibody" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
