產(chǎn)品介紹: The p21 activated kinases (PAK) are critical effectors that link Rho GTPases to cytoskeleton reorganization and nuclear signaling. The PAK proteins are a family of serine/threonine kinases that serve as targets for the small GTP binding proteins, CDC42 and RAC1, and have been implicated in a wide range of biological activities. The protein encoded by this gene is activated by proteolytic cleavage during caspase mediated apoptosis, PAK2 also interacts with and is activated by HIV1 Nef.
Serine/threonine protein kinase that plays a role in a variety of different signaling pathways including cytoskeleton regulation, cell motility, cell cycle progression, apoptosis or proliferation. Acts as downstream effector of the small GTPases CDC42 and RAC1. Activation by the binding of active CDC42 and RAC1 results in a conformational change and a subsequent autophosphorylation on several serine and/or threonine residues. Full-length PAK2 stimulates cell survival and cell growth. Phosphorylates MAPK4 and MAPK6 and activates the downstream target MAPKAPK5, a regulator of F-actin polymerization and cell migration. Phosphorylates JUN and plays an important role in EGF-induced cell proliferation. Phosphorylates many other substrates including histone H4 to promote assembly of H3.3 and H4 into nucleosomes, BAD, ribosomal protein S6, or MBP. Additionally, associates with ARHGEF7 and GIT1 to perform kinase-independent functions such as spindle orientation control during mitosis. On the other hand, apoptotic stimuli such as DNA damage lead to caspase-mediated cleavage of PAK2, generating PAK-2p34, an active p34 fragment that translocates to the nucleus and promotes cellular apoptosis involving the JNK signaling pathway. Caspase-activated PAK2 phosphorylates MKNK1 and reduces cellular translation.

免疫熒光技術(shù)的實(shí)驗(yàn)步驟:
一、準(zhǔn)備好試劑與儀器:
磷酸鹽緩沖鹽水、熒光標(biāo)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(shí)驗(yàn)步驟
1.滴加0.01mol/L,pH7.4的PBS于待檢標(biāo)本片上,十分鐘后棄去,使標(biāo)本保持一定濕度。
2.滴加適當(dāng)稀釋的熒光標(biāo)記的抗體溶液,使其覆蓋標(biāo)本,置于有蓋搪瓷盒內(nèi),保溫一定時(shí)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?fù)u晃振蕩。
4.取出玻片,用濾紙吸去多余水分,但不使標(biāo)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(biāo)本的特異性熒光強(qiáng)度。
