Hypoxia-inducible factor 1-alpha inhibitor (HIF1AN), human, recombinant

Organism: Homo sapiens (Human). Source: Yeast. Expression Region: 2-349aa. Protein Length: Full Length of Mature Protein. Tag Info: C-terminal 6xHis-tagged. Target Protein Sequence: AATAAEAVAS GSGEPREEAG ALGPAWDESQ LRSYSFPTRP IPRLSQSDPR AEELIENEEP VVLTDTNLVY PALKWDLEYL QENIGNGDFS VYSASTHKFL YYDEKKMANF QNFKPRSNRE EMKFHEFVEK LQDIQQRGGE ERLYLQQTLN DTVGRKIVMD FLGFNWNWIN KQQGKRGWGQ LTSNLLLIGM EGNVTPAHYD EQQNFFAQIK GYKRCILFPP DQFECLYPYP VHHPCDRQSQ VDFDNPDYER FPNFQNVVGY ETVVGPGDVL YIPMYWWHHI ESLLNGGITI TVNFWYKGAP TPKRIEYPLK AHQKVAIMRN IEKMLGEALG NPQEVGPLLN TMIKGRYN. 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: Hydroxylates HIF-1 alpha at 'Asn-803' in the C-terminal transactivation domain (CAD). Functions as an oxygen sensor and, under normoxic conditions, the hydroxylation prevents interaction of HIF-1 with transcriptional coactivators including Cbp/p300-interacting transactivator. Involved in transcriptional repression through interaction with HIF1A, VHL and histone deacetylases. Hydroxylates specific Asn residues within ankyrin repeat domains (ARD) of NFKB1, NFKBIA, NOTCH1, ASB4, PPP1R12A and several other ARD-containing proteins. Also hydroxylates Asp and His residues within ARDs of ANK1 and TNKS2, respectively. Negatively regulates NOTCH1 activity, accelerating myogenic differentiation. Positively regulates ASB4 activity, promoting vascular differentiation.
