NCBI and Uniprot Product Information
Uniprot Description
Function: Enhances virion budding, by targeting human CD4 and Tetherin/BST2 to proteasome degradation. Degradation of CD4 prevents any unwanted premature interactions between viral Env and its receptor human CD4 in the endoplasmic reticulum. Degradation of antiretroviral protein Tetherin/BST2 is important for virion budding, as BST2 tethers new viral particles to the host cell membrane. Mechanistically, Vpu bridges either CD4 or BST2 to BTRC, a substrate recognition subunit of the Skp1/Cullin/F-box protein E3 ubiquitin ligase, induces their ubiquitination and subsequent proteasomal degradation. The alteration of the E3 ligase specificity by Vpu seems to interfere with the degradation of host IKBKB, leading to NF-kappa-B down-regulation and subsequent apoptosis. Ion channel activity has also been suggested, however, formation of cation-selective channel has been reconstituted ex-vivo in lipid bilayers. It is thus unsure that this activity plays a role in vivo
By similarity.
Enzyme regulation: Ion channel activity is inhibited by hexamethylene amiloride in vitro
By similarity.
Subunit structure: May form pentamers or hexamers. Forms ternary complexes, by interacting with human CD4 and BTRC, and with human BST2 and BTRC
By similarity.
Subcellular location: Host membrane; Single-pass type I membrane protein
By similarity.
Domain: The N-terminal and transmembrane domains are required for proper virion budding, whereas the cytoplasmic domain is required for CD4 degradation. The cytoplasmic domain is composed of 2 amphipathic alpha helix
By similarity.
Post-translational modification: Phosphorylated by host CK2. This phosphorylation is necessary for interaction with human BRCP and degradation of CD4
By similarity.
Miscellaneous: HIV-1 lineages are divided in three main groups, M (for Major), O (for Outlier), and N (for New, or Non-M, Non-O). The vast majority of strains found worldwide belong to the group M. Group O seems to be endemic to and largely confined to Cameroon and neighboring countries in West Central Africa, where these viruses represent a small minority of HIV-1 strains. The group N is represented by a limited number of isolates from Cameroonian persons. The group M is further subdivided in 9 clades or subtypes (A to D, F to H, J and K).
Sequence similarities: Belongs to the HIV-1 VPU protein family.

Product Notes
The VPU vpu (Catalog #AAA7164803) is an Antibody produced from Rabbit and is intended for research purposes only. The product is available for immediate purchase. The Rabbit anti-Human immunodeficiency virus type 1 group M subtype A (isolate Z321)(HIV-1) VPU Polyclonal Antibody reacts with Human immunodeficiency virus type 1 group M subtype A (isolate Z321)(HIV-1) and may cross-react with other species as described in the data sheet. AAA Biotech's VPU can be used in a range of immunoassay formats including, but not limited to, ELISA (EIA), WB (Western Blot) (ensure identification of antigen). Researchers should empirically determine the suitability of the VPU vpu 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 "VPU, 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
