Description:

TRIM5-alpha is a protein that is found in the cells of many mammals and fends of various retrovirus infections. It protects monkeys from infection with HIV-1, and humans from infection with some other viruses. If a retrovirus has entered a cell, it needs to shed its capsid in order to reversely transcribe its genes, so that they can be expressed by the host cell. It is believed that TRIM5 alpha, which is present in the cytoplasm, somehow recognizes the capsid and blocks its shedding, thereby stopping the virus in its tracks. It thus represents an intracellular defense completely separate from the rest of the body's immune system.

Research Background

Function:

Capsid-specific restriction factor that prevents infection from non-host-adapted retroviruses. Blocks viral replication early in the life cycle, after viral entry but before reverse transcription. In addition to acting as a capsid-specific restriction factor, also acts as a pattern recognition receptor that activates innate immune signaling in response to the retroviral capsid lattice. Binding to the viral capsid triggers its E3 ubiquitin ligase activity, and in concert with the heterodimeric ubiquitin conjugating enzyme complex UBE2V1-UBE2N (also known as UBC13-UEV1A complex) generates 'Lys-63'-linked polyubiquitin chains, which in turn are catalysts in the autophosphorylation of the MAP3K7/TAK1 complex (includes TAK1, TAB2, and TAB3). Activation of the MAP3K7/TAK1 complex by autophosphorylation results in the induction and expression of NF-kappa-B and MAPK-responsive inflammatory genes, thereby leading to an innate immune response in the infected cell. Restricts infection by N-tropic murine leukemia virus (N-MLV), equine infectious anemia virus (EIAV), simian immunodeficiency virus of macaques (SIVmac), feline immunodeficiency virus (FIV), and bovine immunodeficiency virus (BIV). Plays a role in regulating autophagy through activation of autophagy regulator BECN1 by causing its dissociation from its inhibitors BCL2 and TAB2. Also plays a role in autophagy by acting as a selective autophagy receptor which recognizes and targets HIV-1 capsid protein p24 for autophagic destruction.

Post-translational Modifications:

Degraded in a proteasome-independent fashion in the absence of viral infection but in a proteasome-dependent fashion following exposure to restriction sensitive virus.

Autoubiquitinated in a RING finger- and UBE2D2-dependent manner. Monoubiquitinated by TRIM21. Deubiquitinated by Yersinia YopJ. Ubiquitination may not lead to proteasomal degradation.

Subcellular Location:

Cytoplasm. Nucleus.
Note: Predominantly localizes in cytoplasmic bodies (PubMed:12878161, PubMed:20357094). Localization may be influenced by the coexpression of other TRIM proteins, hence partial nuclear localization is observed in the presence of TRIM22 or TRIM27 (By similarity). In cytoplasmic bodies, colocalizes with proteasomal subunits and SQSTM1 (By similarity).

Subunit Structure:

Can form homodimers and homotrimers. In addition to lower-order dimerization, also exhibits a higher-order multimerization and both low- and high-order multimerizations are essential for its restriction activity. Isoform Delta interacts with BTBD1 and BTBD2. Interacts with PSMC4, PSMC5, PSMD7 and HSPA8/HSC70 (By similarity). Interacts (via B30.2/SPRY domain) with HSPA1A/B. Interacts with PSMC2, MAP3K7/TAK1, TAB2 and TAB3. Interacts with SQSTM1. Interacts with TRIM6 and TRIM34. Interacts with ULK1 (phosphorylated form), GABARAP, GABARAPL1, GABARAPL2, MAP1LC3A, MAP1LC3C and BECN1.

Similarity:

The B box-type zinc finger domain and the coiled-coil domain contribute to the higher and low order multimerization respectively which is essential for restriction activity (PubMed:22482711). The coiled coil domain is important for higher order multimerization by promoting the initial dimerization (By similarity).

The B30.2/SPRY domain acts as a capsid recognition domain. Polymorphisms in this domain explain the observed species-specific differences among orthologs (PubMed:22482711).

The RING-type zinc finger domain confers E3 ubiquitin ligase activity and is essential for retrovirus restriction activity, autoubiquitination and higher-order multimerization.

Belongs to the TRIM/RBCC family.

Catalog Number :

BF0206-BP
(Blocking peptide available as BF0206-BP)

Price/Size :

$350/1mg.
Tips: For phospho antibody, we provide phospho peptide(0.5mg) and non-phospho peptide(0.5mg).

Function :

Blocking peptides are peptides that bind specifically to the target antibody and block antibody binding. These peptide usually contains the epitope recognized by the antibody. Antibodies bound to the blocking peptide no longer bind to the epitope on the target protein. This mechanism is useful when non-specific binding is an issue, for example, in Western blotting (immunoblot) and immunohistochemistry (IHC). By comparing the staining from the blocked antibody versus the antibody alone, one can see which staining is specific; Specific binding will be absent from the western blot or immunostaining performed with the neutralized antibody.

Format and storage :

Synthetic peptide was lyophilized with 100% acetonitrile and is supplied as a powder. Reconstitute with 0.1 ml DI water for a final concentration of 10 mg/ml.The purity is >90%,tested by HPLC and MS.Storage Maintain refrigerated at 2-8°C for up to 6 months. For long term storage store at -20°C.

Precautions :

This product is for research use only. Not for use in diagnostic or therapeutic procedures.

IMPORTANT: For western blots, incubate membrane with diluted antibody in 5% w/v milk , 1X TBS, 0.1% Tween®20 at 4°C with gentle shaking, overnight.
