产品介绍 NFkB is formed through the association of multiple subunits, either as a homodimer or heterodimer. Subunits have been identified as p50 (NFkB1), p65 (RelA), c-Rel, RelB and p52 (NFkB2). The classic NFkB form exists as a p50-p65 heterodimer and predominates in many cell types. Many of the possible combinatorial forms of homo- and heterodimers have been identified and growing evidence indicates that different forms of NFkB have different functions in cells. Interestingly, both the p50 and p52 subunits are derived from the precursor proteins p105 and p100 respectively, that each contain multiple copies of the so called ankyrin repeat at their C termini. Nuclear translocation of NFkB is confirmed by the use of electrophorectic mobility shift assays or by immunoblotting with nuclear extracts. The subunit composition of NFkB is confirmed by the use of antibodies that "supershift" the DNA/protein complex.
Function ：
NF-kappa-B is a pleiotropic transcription factor present in almost all cell types and is the endpoint of a series of signal transduction events that are initiated by a vast array of stimuli related to many biological processes such as inflammation, immunity, differentiation, cell growth, tumorigenesis and apoptosis. NF-kappa-B is a homo- or heterodimeric complex formed by the Rel-like domain-containing proteins RELA/p65, RELB, NFKB1/p105, NFKB1/p50, REL and NFKB2/p52. The dimers bind at kappa-B sites in the DNA of their target genes and the individual dimers have distinct preferences for different kappa-B sites that they can bind with distinguishable affinity and specificity. Different dimer combinations act as transcriptional activators or repressors, respectively. NF-kappa-B is controlled by various mechanisms of post-translational modification and subcellular compartmentalization as well as by interactions with other cofactors or corepressors. NF-kappa-B complexes are held in the cytoplasm in an inactive state complexed with members of the NF-kappa-B inhibitor (I-kappa-B) family. In a conventional activation pathway, I-kappa-B is phosphorylated by I-kappa-B kinases (IKKs) in response to different activators, subsequently degraded thus liberating the active NF-kappa-B complex which translocates to the nucleus. In a non-canonical activation pathway, the MAP3K14-activated CHUK/IKKA homodimer phosphorylates NFKB2/p100 associated with RelB, inducing its proteolytic processing to NFKB2/p52 and the formation of NF-kappa-B RelB-p52 complexes. The NF-kappa-B heterodimeric RelB-p52 complex is a transcriptional activator. The NF-kappa-B p52-p52 homodimer is a transcriptional repressor. NFKB2 appears to have dual functions such as cytoplasmic retention of attached NF-kappa-B proteins by p100 and generation of p52 by a cotranslational processing. The proteasome-mediated process ensures the production of both p52 and p100 and preserves their independent function. p52 binds to the kappa-B consensus sequence 5'-GGRNNYYCC-3', located in the enhancer region of genes involved in immune response and acute phase reactions. p52 and p100 are respectively the minor and major form; the processing of p100 being relatively poor. Isoform p49 is a subunit of the NF-kappa-B protein complex, which stimulates the HIV enhancer in synergy with p65.
Subunit ：
Component of the NF-kappa-B RelB-p52 complex. Homodimer; component of the NF-kappa-B p52-p52 complex. Component of the NF-kappa-B p65-p52 complex. Component of the NF-kappa-B p52-c-Rel complex. NFKB2/p52 interacts with NFKBIE. Component of a complex consisting of the NF-kappa-B p50-p50 homodimer and BCL3. Directly interacts with MEN1.
Subcellular Location ：
Nucleus. Cytoplasm. Note=Nuclear, but also found in the cytoplasm in an inactive form complexed to an inhibitor (I-kappa-B).
Post-translational modifications ：
While translation occurs, the particular unfolded structure after the GRR repeat promotes the generation of p52 making it an acceptable substrate for the proteasome. This process is known as cotranslational processing. The processed form is active and the unprocessed form acts as an inhibitor (I kappa B-like), being able to form cytosolic complexes with NF-kappa B, trapping it in the cytoplasm. Complete folding of the region downstream of the GRR repeat precludes processing.
Subsequent to MAP3K14-dependent serine phosphorylation, p100 polyubiquitination occurs then triggering its proteasome-dependent processing.
Constitutive processing is tightly suppressed by its C-terminal processing inhibitory domain, named PID, which contains the death domain.
DISEASE ：
Note=A chromosomal aberration involving NFKB2 is found in a case of B-cell non Hodgkin lymphoma (B-NHL). Translocation t(10;14)(q24;q32) with IGHA1. The resulting oncogene is also called Lyt-10C alpha variant.
Note=A chromosomal aberration involving NFKB2 is found in a cutaneous T-cell leukemia (C-TCL) cell line. This rearrangement produces the p80HT gene which encodes for a truncated 80 kDa protein (p80HT).
Note=In B-cell leukemia (B-CLL) cell line, LB40 and EB308, can be found after heterogeneous chromosomal aberrations, such as internal deletions.
Similarity ：
Contains 7 ANK repeats.
Contains 1 death domain.
Contains 1 RHD (Rel-like) domain.

细胞核因子/k基因结合核因子 p52/p100抗体几种抗体概述：
1.抗角蛋白抗体（AKA），又称为抗丝集蛋白抗体或抗角质层抗体。AKA是类风湿关节炎早期诊断和判断预后的指标之一,其对RA患者的诊断的特异性为94% ,而其敏感性为47% ,并是一种鉴别RA和与多发性关节炎相关的丙型肝炎患者的有效检验标记物。
2.抗核周因子( APF)， 是定位于口腔黏附膜细胞胞质内的颗粒性蛋白复合物。可在RA患者的血清和关节液中测出，与性别、年龄无关。APF显示了较强的特异性（73%～99%）和敏感性。用间接免疫荧光法检测，方法精密度较差。
3.抗环瓜氨酸肽抗体（CCP），具有相对好的敏感度和特异性。其实，抗核周因子和抗角蛋白抗体，与CCP在化学结构上具有相关性，它们的表位都含有瓜氨酸，称为瓜氨酸相关自身免疫系统。
实验原理 :
（1）特异性结合抗原：抗体本身不能直接溶解或杀伤带有特异抗原的靶细胞，通常需要补体或吞噬细胞等共同发挥效应以清除病原微生物或导致病理损伤。然而，抗体可通过与病毒或毒素的特异性结合，直接发挥中和病毒的作用。
（2）活补体：IgM、IgG1、IgG2和IgG3可通过经典途径激活补体，凝聚的IgA、IgG4和IgE可通过替代途径激活补体。
（3）结合细胞：不同类别的免疫球蛋白，可结合不同种的细胞，参与免疫应答。
（4）可通过胎盘及粘膜：免疫球蛋白G（IgG）能通过胎盘进入胎儿血流中，使胎儿形成自然被动
免疫。免疫球蛋白A（IgA）可通过消化道及呼吸道粘膜，是粘膜局部抗感染免疫的主要因素。
（5）具有抗原性：抗体分子是一种蛋白质，也具有刺机体产生免疫应答的性能。不同的免疫球蛋白分子，各具有不同的抗原性。
（6）抗体对理化因子的抵抗力与一般球蛋白相同：不耐热，60～70℃即被破坏。各种酶及能使蛋白质凝固变性的物质，均能破坏抗体的作用。抗体可被中性盐类沉淀。在上常可用硫酸铵或硫酸钠从免疫血清中沉淀出含有抗体的球蛋白，再经透析法将其纯化。
