共軛：

Avi-tag Biotinylated
E. coli biotin ligase (BirA) is highly specific in covalently attaching biotin to the 15 amino acid AviTag peptide. This recombinant protein was biotinylated in vivo by AviTag-BirA technology, which method is BriA catalyzes amide linkage between the biotin and the specific lysine of the AviTag.

The tag type will be determined during production process. If you have specified tag type, please tell us and we will develop the specified tag preferentially.
產品提供形式：

Lyophilized powder
Note: We will preferentially ship the format that we have in stock, however, if you have any special requirement for the format, please remark your requirement when placing the order, we will prepare according to your demand.
復溶：

We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20℃/-80℃. Our default final concentration of glycerol is 50%. Customers could use it as reference.
儲存條件：

Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
保質期：

The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself.
Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
貨期：

Delivery time may differ from different purchasing way or location, please kindly consult your local distributors for specific delivery time.
Note: All of our proteins are default shipped with normal blue ice packs, if you request to ship with dry ice, please communicate with us in advance and extra fees will be charged.
注意事項：

Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

靶點詳情

功能：

Non-catalytic component of the 20S core proteasome complex involved in the proteolytic degradation of most intracellular proteins. This complex plays numerous essential roles within the cell by associating with different regulatory particles. Associated with two 19S regulatory particles, forms the 26S proteasome and thus participates in the ATP-dependent degradation of ubiquitinated proteins. The 26S proteasome plays a key role in the maintenance of protein homeostasis by removing misfolded or damaged proteins that could impair cellular functions, and by removing proteins whose functions are no longer required. Associated with the PA200 or PA28, the 20S proteasome mediates ubiquitin-independent protein degradation. This type of proteolysis is required in several pathways including spermatogenesis (20S-PA200 complex) or generation of a subset of MHC class I-presented antigenic peptides (20S-PA28 complex). SMAD1/OAZ1/PSMB4 complex mediates the degradation of the CREBBP/EP300 repressor SNIP1.

1. High PSMB4 expression is associated with breast cancer. PMID: 30066880
2. PSMB4 knockdown decreased the expression levels of MMP2, MMP9 and cathepsin B and decreased proliferation, migration and invasion abilities in human GBM cells. PMID: 29414809
3. We further identified miR-148b as a negative regulator of proteasome beta-4 subunit. Enforced expression of miR-148b resulted in vitro growth inhibition of melanoma cells, whereas this inhibition was further abolished by enforced expression of proteasome beta-4 subunit PMID: 28656878
4. Our findings implied that PSMB4 is involved in the progression of EOC (epithelial ovarian cancer) and could serve as potential therapeutical target of EOC. These data suggested that PSMB4 may promote cell proliferation via the NF-kappaB-target gene in EOC (epithelial ovarian cancer) PMID: 26439929
5. Taken together, our results demonstrated that PSMB4 regulated MM cell growth in part by activating NF-kappaB-miR-21 signaling, which may represent promising targets for novel specific therapies. PMID: 25656574
6. Data indicate that recruitment of proteasomes into mutant huntingtin (mHTT) protein initiated inclusion bodies (IBs) was observed when the PSMB4-GFP was co-expressed with mHTT. PMID: 24291262
7. proteasome subunit beta type 4 (PSMB4), the beta7 subunit of the 20S core complex, was identified as a direct binding partner of CRBN. PMID: 23026050
