產(chǎn)品介紹:This gene encodes a member of the sirtuin family of proteins, homologs to the yeast Sir2 protein. Members of the sirtuin family are characterized by a sirtuin core domain and grouped into four classes. The functions of human sirtuins have not yet been determined; however, yeast sirtuin proteins are known to regulate epigenetic gene silencing and suppress recombination of rDNA. Studies suggest that the human sirtuins may function as intracellular regulatory proteins with mono-ADP-ribosyltransferase activity. The protein encoded by this gene is included in class I of the sirtuin family. Alternative splicing results in multiple transcript variants.
NAD-dependent protein deacetylase, which regulates processes such as apoptosis and muscle differentiation by deacetylating key proteins. Deacetylates 'Lys-382' of p53/TP53 and impairs its ability to induce proapoptotic program and modulate cell senescence. Deacetylates TAF1B and thereby represses rDNA transcription by the RNA polymerase I. Deacetylates 'Lys-266' of SUV39H1, leading to its activation. Deacetylates 'Lys-26' of HIST1H1E. Involved in HES1- and HEY2-mediated transcriptional repression. Inhibits skeletal muscle differentiation by deacetylating PCAF and MYOD1. May serve as a sensor of the cytosolic ratio of NAD(+)/NADH, which is essential in skeletal muscle cell differentiation. Deacetylates 'Lys-16' of histone H4 (in vitro). Component of the eNoSC (energy-dependent nucleolar silencing) complex, a complex that mediates silencing of rDNA in response to intracellular energy status and acts by recruiting histone-modifying enzymes. The eNoSC complex is able to sense the energy status of cell: upon glucose starvation, elevation of NAD(+)/NADP(+) ratio activates SIRT1, leading to histone H3 deacetylation followed by dimethylation of H3 at 'Lys-9' (H3K9me2) by SUV39H1 and the formation of silent chromatin in the rDNA locus. Deacetylates H2A. In case of HIV-1 infection, interacts with and deacetylates the viral Tat protein. Deacetylates APEX1 at 'Lys-6' and 'Lys-7'. Stimulates cellular AP endonuclease activity by promoting the association of APEX1 to XRCC1.

抗體的結(jié)構(gòu):
抗體是具有4條多肽鏈的對稱結(jié)構(gòu),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(lián)結(jié)形成一個由4條多肽鏈構(gòu)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(qū)和可變區(qū)兩部分。在給定的物種中,不同抗體分子的恒定區(qū)都具有相同的或幾乎相同的氨基酸序列。可變區(qū)位于"Y"的兩臂末端。在可變區(qū)內(nèi)有一小部分氨基酸殘基變化特別強(qiáng)烈,這些氨基酸的殘基組成和排列順序更易發(fā)生變異區(qū)域稱高變區(qū)。高變區(qū)位于分子表面,最多由17個氨基酸殘基構(gòu)成,少則只有2 ~ 3個。高變區(qū)氨基酸序列決定了該抗體結(jié)合抗原抗原的特異性。一個抗體分子上的兩個抗原結(jié)合部位是相同的,位于兩臂末端稱抗原結(jié)合片段(antigen-binding fragment, Fab)。"Y"的柄部稱結(jié)晶片段(crystalline fragment,FC),糖結(jié)合在FC 上。
