產品描述：

牛蛋白S100-A8（S100A8）是一種小分子的鈣調蛋白，參與了多種細胞功能的調節和信號傳導。如果想要重組這種蛋白，可以按照以下步驟進行：
克隆S100A8基因：可以使用PCR技術從牛的基因組DNA中擴增S100A8基因的開放閱讀框（ORF）序列。此外，還需要添加一些啟動子和標簽序列，以便在表達過程中調節基因表達，并且可以方便地檢測到蛋白質。

構建表達載體：將S100A8基因插入表達載體中，可以選擇一些經過驗證的表達載體，如pET系列載體。這些載體中包含了一些促進蛋白表達的元件，如啟動子、增強子、終止子等。

選擇表達宿主菌：可以選擇一些常用的表達宿主菌，如大腸桿菌（E. coli），并在菌株中轉化含有S100A8基因的表達載體。這些宿主菌中還需要添加一些輔助蛋白質，如分泌蛋白、分子伴侶等，以幫助蛋白質的正確折疊和純化。

蛋白表達和純化：在表達宿主菌中誘導S100A8蛋白的表達，并通過細胞破碎和離心等方法提取蛋白質。然后使用親和層析、離子交換層析、凝膠過濾層析等方法對蛋白進行純化。

蛋白質的鑒定和活性檢測：使用SDS-PAGE、Western blot等方法對純化后的S100A8蛋白進行鑒定和定量。此外，還可以使用細胞實驗等方法對S100A8蛋白的生物活性進行檢測，如檢測其對細胞的增殖、分化、遷移等的影響。

靶點詳情

功能：

S100A8 is a calcium- and zinc-binding protein which plays a prominent role in the regulation of inflammatory processes and immune response. It can induce neutrophil chemotaxis and adhesion. Predominantly found as calprotectin (S100A8/A9) which has a wide plethora of intra- and extracellular functions. The intracellular functions include: facilitating leukocyte arachidonic acid trafficking and metabolism, modulation of the tubulin-dependent cytoskeleton during migration of phagocytes and activation of the neutrophilic NADPH-oxidase. Activates NADPH-oxidase by facilitating the enzyme complex assembly at the cell membrane, transferring arachidonic acid, an essential cofactor, to the enzyme complex and S100A8 contributes to the enzyme assembly by directly binding to NCF2/P67PHOX. The extracellular functions involve proinflammatory, antimicrobial, oxidant-scavenging and apoptosis-inducing activities. Its proinflammatory activity includes recruitment of leukocytes, promotion of cytokine and chemokine production, and regulation of leukocyte adhesion and migration. Acts as an alarmin or a danger associated molecular pattern (DAMP) molecule and stimulates innate immune cells via binding to pattern recognition receptors such as Toll-like receptor 4 (TLR4) and receptor for advanced glycation endproducts (AGER). Binding to TLR4 and AGER activates the MAP-kinase and NF-kappa-B signaling pathways resulting in the amplification of the proinflammatory cascade. Has antimicrobial activity towards bacteria and fungi and exerts its antimicrobial activity probably via chelation of Zn(2+) which is essential for microbial growth. Can induce cell death via autophagy and apoptosis and this occurs through the cross-talk of mitochondria and lysosomes via reactive oxygen species (ROS) and the process involves BNIP3. Can regulate neutrophil number and apoptosis by an anti-apoptotic effect; regulates cell survival via ITGAM/ITGB and TLR4 and a signaling mechanism involving MEK-ERK. Its role as an oxidant scavenger has a protective role in preventing exaggerated tissue damage by scavenging oxidants. The iNOS-S100A8/A9 transnitrosylase complex is proposed to direct selective inflammatory stimulus-dependent S-nitrosylation of multiple targets such as GAPDH, ANXA5, EZR, MSN and VIM by recognizing a [IL]-x-C-x-x-[DE] motif; S100A8 seems to contribute to S-nitrosylation site selectivity.
