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.
緩沖液：

Lyophilized from Tris/PBS-based buffer, 6% Trehalose, pH 8.0
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.

靶點詳情

功能：

An anti-sigma factor for extracytoplasmic function (ECF) sigma factor sigma-E (RpoE). ECF sigma factors are held in an inactive form by an anti-sigma factor until released by regulated intramembrane proteolysis (RIP). RIP occurs when an extracytoplasmic signal triggers a concerted proteolytic cascade to transmit information and elicit cellular responses. The membrane-spanning regulatory substrate protein is first cut periplasmically (site-1 protease, S1P, DegS), then within the membrane itself (site-2 protease, S2P, RseP), while cytoplasmic proteases finish degrading the anti-sigma factor, liberating sigma-E. Overexpression of RseA blocks sigma-E from acting, results in cell lysis in stationary phase and temperature-sensitivity above 37 degrees Celsius.
基因功能參考文獻：
1. Results show RseB binds to RseA and inhibits its sequential cleavage, thereby functioning as a negative modulator of this response. PMID: 20512978
2. Although DegS cleavage of RseA is normally activated by binding of the C termini of porins to the PDZ domain of DegS, RseB inhibition is independent of this activation mechanism PMID: 17360428
3. two RseAs bind to the grooves of the dimeric RseB by conserved residues PMID: 17496148
亞細胞定位：

Cell inner membrane; Single-pass type II membrane protein. Note=Following cleavage by DegS the large fragment of the protein is still in the inner membrane and retains its anti-sigma-E activity.
蛋白家族：

RseA family
