UV excision repair protein RAD23 homolog A (RAD23A), human, recombinant

Organism: Homo sapiens (Human). Source: E.coli. Expression Region: 1-363aa. Protein Length: Full Length. Tag Info: N-terminal 10xHis-tagged. Target Protein Sequence: MAVTITLKTL QQQTFKIRME PDETVKVLKE KIEAEKGRDA FPVAGQKLIY AGKILSDDVP IRDYRIDEKN FVVVMVTKTK AGQGTSAPPE ASPTAAPESS TSFPPAPTSG MSHPPPAARE DKSPSEESAP TTSPESVSGS VPSSGSSGRE EDAASTLVTG SEYETMLTEI MSMGYERERV VAALRASYNN PHRAVEYLLT GIPGSPEPEH GSVQESQVSE QPATEAAGEN PLEFLRDQPQ FQNMRQVIQQ NPALLPALLQ QLGQENPQLL QQISRHQEQF IQMLNEPPGE LADISDVEGE VGAIGEEAPQ MNYIQVTPQE KEAIERLKAL GFPESLVIQA YFACEKNENL AANFLLSQNF DDE. Purity: Greater than 90% as determined by SDS-PAGE. Endotoxin: Not test. Biological Activity: n/a. Form: Liquid or Lyophilized powder. Buffer: If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0. Reconstitution: 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 °C/-80 °C. Our default final concentration of glycerol is 50%. Customers could use it as reference. Storage: 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. Notes: Repeated freezing and thawing is not recommended. Store working aliquots at 4 °C for up to one week. Relevance: Multiubiquitin chain receptor involved in modulation of proteasomal degradation. Binds to 'Lys-48'-linked polyubiquitin chains in a length-dependent manner and with a lower affinity to 'Lys-63'-linked polyubiquitin chains. Proposed to be capable to bind simultaneously to the 26S proteasome and to polyubiquitinated substrates and to deliver ubiquitinated proteins to the proteasome., Involved in nucleotide excision repair and is thought to be functional equivalent for RAD23B in global genome nucleotide excision repair (GG-NER) by association with XPC. In vitro, the XPC:RAD23A dimer has NER activity. Can stabilize XPC., (Microbial infection) Involved in Vpr-dependent replication of HIV-1 in non-proliferating cells and primary macrophages. Required for the association of HIV-1 Vpr with the host proteasome.
