Recombinant Human YY1/Transcri

Recombinant Human YY1/Transcriptional repressor protein YY1  (CH59)

 

产品说明(Description)

Recombinant Human Yin and Yang 1 protein/Transcriptional repressor protein YY1 is produced by our E.coli expression system and the target gene encoding Val221-Gly321 is expressed with a 6His tag at the C-terminus. 

Accession #: P25490

Known as: Transcriptional repressor protein YY1;Delta transcription factor;INO80 complex subunit S;NF-E1;Yin and yang 1;INO80S

 

制剂（Formulation）

Lyophilized from a 0.2 μm filtered solution of PBS, pH 7.4.

 

质量控制（Quality Control） 

 

Purity:            Greater than 95% as determined by reducing SDS-PAGE.    

Endotoxin:    Less than 0.1 ng/ug (1 EU/ug) as determined by LAL test.

 

复溶（Reconstitution）

Always centrifuge tubes before opening. Do not mix by vortex or pipetting.
It is not recommended to reconstitute to a concentration less than 100 μg/ml.
Dissolve the lyophilized protein in distilled water.
Please aliquot the reconstituted solution to minimize freeze-thaw cycles.    

 

保存（Storage）

Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks.Reconstituted protein solution can be stored at 4-7°C for 2-7 days.Aliquots of reconstituted samples are stable at < -20°C for 3 months.     

 

背景（Background）

Transcriptional repressor protein YY1（YY1）contains 4 C2H2-type zinc fingers and belongs to the YY transcription factor family. Multifunctional transcription factor exhibits positive and negative control on a large number of cellular and viral genes by binding to sites overlapping the transcription start site. The effect on transcription regulation of the protein is depending upon the context in which it binds and diverse mechanisms of action include direct activation or repression, indirect activation or repression via cofactor recruitment, or activation or repression by disruption of binding sites or conformational DNA changes. Its activity is regulated by transcription factors and cytoplasmic proteins that have been shown to abrogate or completely inhibit YY1-mediated activation or repression.
