產品介紹:This gene encodes a member of the ribosomal S6 kinase family of serine/threonine kinases. The encoded protein responds to mTOR (mammalian target of rapamycin) signaling to promote protein synthesis, cell growth, and cell proliferation. Activity of this gene has been associated with human cancer. Alternatively spliced transcript variants have been observed. The use of alternative translation start sites results in isoforms with longer or shorter N-termini which may differ in their subcellular localizations. There are two pseudogenes for this gene on chromosome 17. [provided by RefSeq, Jan 2013].

Serine/threonine-protein kinase that acts downstream of mTOR signaling in response to growth factors and nutrients to promote cell proliferation, cell growth and cell cycle progression. Regulates protein synthesis through phosphorylation of EIF4B, RPS6 and EEF2K, and contributes to cell survival by repressing the pro-apoptotic function of BAD. Under conditions of nutrient depletion, the inactive form associates with the EIF3 translation initiation complex. Upon mitogenic stimulation, phosphorylation by the mammalian target of rapamycin complex 1 (mTORC1) leads to dissociation from the EIF3 complex and activation. The active form then phosphorylates and activates several substrates in the preinitiation complex, including the EIF2B complex and the cap-binding complex component EIF4B. Also controls translation initiation by phosphorylating a negative regulator of EIF4A, PDCD4, targeting it for ubiquitination and subsequent proteolysis. Promotes initiation of the pioneer round of protein synthesis by phosphorylating POLDIP3/SKAR. In response to IGF1, activates translation elongation by phosphorylating EEF2 kinase (EEF2K), which leads to its inhibition and thus activation of EEF2. Also plays a role in feedback regulation of mTORC2 by mTORC1 by phosphorylating RICTOR, resulting in the inhibition of mTORC2 and AKT1 signaling. Mediates cell survival by phosphorylating the pro-apoptotic protein BAD and suppressing its pro-apoptotic function. Phosphorylates mitochondrial URI1 leading to dissociation of a URI1-PPP1CC complex. The free mitochondrial PPP1CC can then dephosphorylate RPS6KB1 at 'Thr-412', which is proposed to be a negative feedback mechanism for the RPS6KB1 anti-apoptotic function. Mediates TNF-alpha-induced insulin resistance by phosphorylating IRS1 at multiple serine residues, resulting in accelerated degradation of IRS1. In cells lacking functional TSC1-2 complex, constitutively phosphorylates and inhibits GSK3B. May be involved in cytoskeletal rearrangement through binding to neurabin.

免疫熒光技術的實驗步驟：

一、準備好試劑與儀器：

磷酸鹽緩沖鹽水、熒光標記的抗體溶液、緩沖甘油、搪瓷桶三只、有蓋搪瓷盒一只、熒光顯微鏡、玻片架、濾紙、37℃溫箱等。

二、實驗步驟

1.滴加0.01mol/L，pH7.4的PBS于待檢標本片上，十分鐘后棄去，使標本保持一定濕度。

2.滴加適當稀釋的熒光標記的抗體溶液，使其覆蓋標本，置于有蓋搪瓷盒內，保溫一定時間以三十分鐘為參考。

3.取出玻片，置玻片架上，先用0.01mol/L，pH7.4的PBS沖洗后，再按順序過0.01mol/L，pH7.4的PBS三缸浸泡，每缸三到五分鐘，并不停地搖晃振蕩。

4.取出玻片，用濾紙吸去多余水分，但不使標本干燥，加一滴緩沖甘油，以蓋玻片覆蓋。

5.立即用熒光顯微鏡觀察。觀察標本的特異性熒光強度。

抗體的定義：

抗體（antibody），（免疫球蛋白不僅僅只是抗體）是一種由漿細胞（效應B細胞）分泌，被免疫系統用來鑒別與中和外來物質如細菌、病毒等的大型Y形蛋白質，僅被發現存在于脊椎動物的血液等體液中，及其B細胞的細胞膜表面。抗體能識別特定外來物的一個特征，該外來目標被稱為抗原。

抗體的結構：

抗體是具有4條多肽鏈的對稱結構，其中2條較長、相對分子量較大的相同的重鏈(H鏈)；2條較短、相對分子量較小的相同的輕鏈(L鏈)。鏈間由二硫鍵和非共價鍵聯結形成一個由4條多肽鏈構成的單體分子。輕鏈有κ和λ兩種，重鏈有μ、δ、γ、ε和α五種。 整個抗體分子可分為恒定區和可變區兩部分。在給定的物種中，不同抗體分子的恒定區都具有相同的或幾乎相同的氨基酸序列。可變區位于"Y"的兩臂末端。在可變區內有一小部分氨基酸殘基變化特別強烈，這些氨基酸的殘基組成和排列順序更易發生變異區域稱高變區。高變區位于分子表面，最多由17個氨基酸殘基構成，少則只有2 ～ 3個。高變區氨基酸序列決定了該抗體結合抗原抗原的特異性。一個抗體分子上的兩個抗原結合部位是相同的，位于兩臂末端稱抗原結合片段(antigen-binding fragment, Fab)。"Y"的柄部稱結晶片段(crystalline fragment,FC)，糖結合在FC 上。
