通用注释
亚单元:
Self-associates; enforced oligomerization induces apoptosis, NF-kappa-B regulation and interleukin-1 beta secretion. Homooligomers can form disk-like particles of approximately 12 nm diameter and approximately 1 nm height. Next to isorm 1 also isoform 2 and isoform 3 may be involved in oligomerization leading to functional regulation. Component of several inflammasomes containing one pattern recognition receptor/sensor, such as NLRP1, NLRP2, NLRP3, AIM2, MEFV or NOD2, and probably NLRC4, NLRP12 or IFI16. Major component of the ASC pyroptosome, a 1-2 um supramolecular assembly (one per macrophage cell) which consists of oligomerized PYCARD dimers and CASP1. Interacts with CASP1 (precursor form); the interaction induces activation of CASP1 leading to the processing of interleukin-1 beta; PYCARD competes with RIPK2 for binding to CASP1. Interacts with NLRP3; the interaction requires the homooligomerization of NLRP3. Interacts with NLRP2, NLRC4, MEFV, CARD16, AIM2, IFI16, NOD2, DDX58, RIPK2, PYDC1, PYDC2, NLRP10, CASP8, CHUK, IKBKB and BAX.
功能:
Functions as key mediator in apoptosis and inflammation. Promotes caspase-mediated apoptosis involving predominantly caspase-8 and also caspase-9 in a probable cell type-specific manner. Involved in activation of the mitochondrial apoptotic pathway, promotes caspase-8-dependent proteolytic maturation of BID independently of FADD in certain cell types and also mediates mitochondrial translocation of BAX and activates BAX-dependent apoptosis coupled to activation of caspase-9, -2 and -3. Involved in macrophage pyroptosis, a caspase-1-dependent inflammatory form of cell death and is the major constituent of the ASC pyroptosome which forms upon potassium depletion and rapidly recruits and activates caspase-1. In innate immune response believed to act as an integral adapter in the assembly of the inflammasome which activates caspase-1 leading to processing and secretion of proinflammatory cytokines. The function as activating adapter in different types of inflammasomes is mediated by the pyrin and CARD domains and their homotypic interactions. Required for recruitment of caspase-1 to inflammasomes containing certain pattern recognition receptors, such as NLRP2, NLRP3, AIM2 and probably IFI16. In the NLRP1 and NLRC4 inflammasomes seems not be required but facilitates the processing of procaspase-1. In cooperation with NOD2 involved in an inflammasome activated by bacterial muramyl dipeptide leading to caspase-1 activation. May be involved in DDX58-triggered proinflammatory responses and inflammasome activation. Isoform 2 may have a regulating effect on the function as inflammasome adapter. Isoform 3 seems to inhibit inflammasome-mediated maturation of interleukin-1 beta. In collaboration with AIM2 which detects cytosolic double-stranded DNA may also be involved in a caspase-1-independent cell death that involves caspase-8. In adaptive immunity may be involved in maturation of dendritic cells to stimulate T-cell immunity and in cytoskeletal rearrangements coupled to chemotaxis and antigen uptake may be involved in post-transcriptional regulation of the guanine nucleotide exchange factor DOCK2; the latter function is proposed to involve the nuclear form. Also involved in transcriptional activation of cytokines and chemokines independent of the inflammasome; this function may involve AP-1, NF-kappa-B, MAPK and caspase-8 signaling pathways. For regulation of NF-kappa-B activating and inhibiting functions have been reported. Modulates NF-kappa-B induction at the level of the IKK complex by inhibiting kinase activity of CHUK and IKBK. Proposed to compete with RIPK2 for association with CASP1 thereby down-regulating CASP1-mediated RIPK2-dependent NF-kappa-B activation and activating interleukin-1 beta processing.

Nucleus
Upstream of caspase activation, a redistribution from the cytoplasm to the aggregates occurs. These appear as hollow, perinuclear spherical, ball-like structures. Upon NLRP3 inflammasome activation redistributes to the perinuclear space localizing to endoplasmic reticulum and mitochondria. Localized primarily to the nucleus in resting monocytes/macrophages and rapidly redistributed to the cytoplasm upon pathogen infection. Localized to large cytoplasmic aggregate appearing as a speck containing AIM2, PYCARD, CASP8 and bacterial DNA after infection with Francisella tularensis (By similarity).

人细胞凋亡相关斑点样蛋白(PYCARD)重组蛋白是否是无菌的？
蛋白试剂瓶和蛋白保存液是经过高压灭菌的，但也不能保证蛋白是完全无菌的。如果要求蛋白是无菌的，可以用0.2微米的滤器对蛋白进行过滤。
[2].
人细胞凋亡相关斑点样蛋白(PYCARD)重组蛋白的保存缓冲液是什么？
纯化后的蛋白保存在PBS（58mM Na2HPO4, 17mM NaH2PO4, 68mM NaCl, pH7.4）里，并往里面加入500mM咪唑和10%甘油。
[3].
怎样确定人细胞凋亡相关斑点样蛋白(PYCARD)重组蛋白的浓度？
蛋白浓度的确定没有一个统一的标准，这主要取决于蛋白的氨基酸序列。伊艾博是根据不同测试的组合来测定蛋白浓度。考马斯亮蓝法、BCA法、氨基酸序列和氨基酸全序列分析法等都用来测定蛋白浓度。
[4].
人细胞凋亡相关斑点样蛋白(PYCARD)重组蛋白蛋白保存条件是怎样的？
蛋白应保存在 -20℃或 -80℃条件下，为了避免反复冻融，可以将蛋白分装成小份保存。
[5].
人细胞凋亡相关斑点样蛋白(PYCARD)重组蛋白是否可以用于活体实验？
重组蛋白没有用于任何的活体实验，因此蛋白的活性和半衰期是不确定的。
[6].
人细胞凋亡相关斑点样蛋白(PYCARD)重组蛋白的保质期是多久？
在适当的保存条件下，从购买之日起蛋白可以稳定保存6-12个月。适当的保存条件是:蛋白保存在-20°C o或 -80℃，保证蛋白的保存浓度高于0.1mg/ml，限制蛋白反复冻融的次数。我们公司常规的质量检测保证所有产品在销售时都有可接受的生物活性。但是我们不能控制终端用户蛋白的保存条件。如果产品在有效期内出现问题，请联系我们的技术支持。
