目标基因介绍   DNA- and RNA binding protein, involved in several nuclear processes (PubMed:11525732, PubMed:12403470, PubMed:26571461). Binds the conventional octamer sequence in double-stranded DNA (PubMed:11525732, PubMed:12403470, PubMed:26571461). Also binds single-stranded DNA and RNA at a site independent of the duplex site (PubMed:11525732, PubMed:12403470, PubMed:26571461). Involved in pre-mRNA splicing, probably as a heterodimer with SFPQ (PubMed:11525732, PubMed:12403470, PubMed:26571461). Interacts with U5 snRNA, probably by binding to a purine-rich sequence located on the 3' side of U5 snRNA stem 1b (PubMed:12403470). Together with PSPC1, required for the formation of nuclear paraspeckles (PubMed:22416126). The SFPQ-NONO heteromer associated with MATR3 may play a role in nuclear retention of defective RNAs (PubMed:11525732). The SFPQ-NONO heteromer may be involved in DNA unwinding by modulating the function of topoisomerase I/TOP1 (PubMed:10858305). The SFPQ-NONO heteromer may be involved in DNA non-homologous end joining (NHEJ) required for double-strand break repair and V(D)J recombination and may stabilize paired DNA ends (PubMed:15590677). In vitro, the complex strongly stimulates DNA end joining, binds directly to the DNA substrates and cooperates with the Ku70/G22P1-Ku80/XRCC5 (Ku) dimer to establish a functional preligation complex (PubMed:15590677). NONO is involved in transcriptional regulation. The SFPQ-NONO-NR5A1 complex binds to the CYP17 promoter and regulates basal and cAMP-dependent transcriptional activity (PubMed:11897684). NONO binds to an enhancer element in long terminal repeats of endogenous intracisternal A particles (IAPs) and activates transcription (By similarity). Regulates the circadian clock by repressing the transcriptional activator activity of the CLOCK-BMAL1 heterodimer (By similarity). Important for the functional organization of GABAergic synapses (By similarity). Plays a specific and important role in the regulation of synaptic RNAs and GPHN/gephyrin scaffold structure, through the regulation of GABRA2 transcript (By similarity). Plays a key role during neuronal differentiation by recruiting TET1 to genomic loci and thereby regulating 5-hydroxymethylcytosine levels (By similarity). Plays a role in the regulation of DNA virus-mediated innate immune response by assembling into the HDP-RNP complex, a complex that serves as a platform for IRF3 phosphorylation and subsequent innate immune response activation through the cGAS-STING pathway (PubMed:28712728, PubMed:30270045). Promotes activation of the cGAS-STING pathway in response to HIV-2 infection: acts by interacting with HIV-2 Capsid protein p24, thereby promoting detection of viral DNA by CGAS, leading to CGAS-mediated inmmune activation (PubMed:30270045). In contrast, the weak interaction with HIV-1 Capsid protein p24 does not allow activation of the cGAS-STING pathway (PubMed:30270045).

应用   体内和体外测定
复苏   1)在37℃水浴中预热完全培养基。 2)将冻存管在 37℃水浴中解冻1-2分钟。 3)将冻存管转移到生物安全柜中,并用70%乙醇擦拭表面。 4)拧开冻存管管盖,将细胞悬液轻轻转移到含有9mL完全培养基的无菌离心管中。 5)在室温下以125g离心5-7分钟,弃上清。 6)用5mL的完整培养基重悬细胞沉淀,将细胞悬液转移到T25培养瓶中。 7)将细胞转移到37℃,5% CO2的培养箱中培养。 8)参考传代比例:1/2到1/3传代,2-5天长满。
传代   1)待培养瓶中细胞汇合度至80%-90%以上,可进行细胞传代。 2)将培养基、PBS、胰酶(0.25%Trypsin_EDTA Gibco 25200-056)等从4℃冰箱中拿出,置于37℃水浴中温度接近37℃时取出并在瓶子表面喷洒75%酒精后置于生物安全柜中。 3)从培养箱中取出待传代的培养瓶,瓶身喷洒75%酒精后置于生物安全柜中。 4)为避免冲散细胞,沿培养瓶上壁PBS润洗细胞,清洗细胞后弃去,T25加2mL。 5)加入对应体积的胰酶(T75加1.5mL,T25加0.5mL),并轻轻晃动瓶身使胰酶平铺满细胞底部。可根据实际情况适当增加或减少用量。约1-2min后大部分细胞脱落时,加入对应体积的完全培养基终止消化,并用5mL移液管轻轻吹打至细胞全部脱落。 6)将细胞悬液转移至15mL离心管,悬液300g离心5min,弃上清。 7)移取5mL完全培养基重悬细胞,按需求调整接种比例,并补充培养瓶中完全培养基,T75加至13-15mL,T25加至5mL,加1%双抗。 8)盖上瓶盖拧紧后轻轻晃动瓶身,使细胞混合均匀后置于37℃,5% CO4培养箱中。
细胞冻存   1)准备冻存液,并提前预冷。 2)确保待冻存的细胞满足冻存要求,用显微镜检查以下状态:健康的外观及形态特征、所处生长周期(对数晚期)、无污染或衰退迹象。 3)对细胞进行消化及离心处理(具体步骤参考传代培养流程) 4)按照每管1mL的量添加冻存液重悬细胞,吹打均匀后分装至冻存管。 5)将细胞放在程序降温盒中,在-80℃冰箱中冷冻。 6)后续将细胞转移到液氮罐中,以便长期储存。
