Application
人半胱天冬酶1已用于:
- 以Rab 相互作用溶酶体蛋白(RILP)进行的体外裂解分析。
- 人单核细胞中半胱天冬酶-3/7(THP1)的裂解。
- 在SDS-PAGE中消化蛋白质样品,用于理解保守的细胞外环半胱氨酸在结构和功能方面的重要性。
- 通过Ac-YVAD-AMC底物进行的荧光测定来评估化合物的抑制活性。
Biochem/physiol Actions
半胱天冬酶 1催化促炎细胞因子白介素(IL)-1前体β转化为其活性形式。它具有广泛的底物特异性,并且是一种细胞凋亡调节剂。半胱天冬酶 -1间接参与了冷吡啉相关周期性综合征(CAPS)的病理过程。它是与多发性硬化症(MS)病变相关的多重炎症小体相关蛋白,是抑制剂筛选的主要靶标。
用于筛选半胱天冬酶抑制剂、研究酶调控和动力学、确定靶底物或作为半胱天冬酶-1 活性分析中的阳性对照。
General description
研究领域:细胞凋亡
半胱天冬酶1,也称为白介素(IL)-1转换酶,位于人11q22.3。它属于天冬氨酸特异性半胱氨酸蛋白酶家族,主要被合成为procaspase-1酶原,该酶随后在蛋白自水解(autoproteolysis)后具有催化活性。具有酶活性的半胱天冬酶-1包含两个p20 / p10异质二聚体,这使其成为四聚体。

Constitutive- and immunoproteasomes are part of the ubiquitin-proteasome system (UPS), which is responsible for the protein homeostasis. Selective inhibition of the immunoproteasome offers opportunities for the treatment of numerous diseases, including inflammation, autoimmune diseases, and hematologic malignancies.

Caspase-1, formerly known as interleukin (IL)-1-converting enzyme is best established as the protease responsible for the processing of the key pro-inflammatory cytokine IL-1β from an inactive precursor to an active, secreted molecule. Thus, caspase-1 is regarded as a key mediator

Caspase-1, a mediator of the posttranslational processing of IL-1beta and IL-18, requires an aspartic acid in the P1 position of its substrates. The mechanisms of caspase-1 activation remain poorly understood despite numerous structures of the enzyme complexed with aspartate-based inhibitors.
