UCH37 탐지용 프로브 및 이의 용도{PROBE FOR DETECTING UCH37 AND USES THEREOF}Probe for detecting UCH37 and uses thereof {PROBE FOR DETECTING UCH37 AND USES THEREOF}

본 발명은 신규한 UCH37 탐지용 프로브와 상기 프로브를 다양하게 이용하는 기술에 관한 것이다.The present invention relates to a novel UCH37 detection probe and a technology for using the probe in various ways.

유비퀴틴 프로테아좀 시스템(ubiquitin proteasome system)은 세포의 성장과 분열, 세포 주기, 세포 내 신호전달, 세포 자살 등에서 중요한 조절 기작으로서, 이 조절 기작을 통하여 기질로 작용하는 단백질이 프로테아좀에 의해 분해된다. 즉, 다중 유비퀴틴 단백질 사슬이 기질에 공유 결합을 하고 이들은 20S CP(catalytic core particle)와 19S RP(regulatory particle)로 구성된 26S 프로테아좀에 의해 인식되어 분해되는 과정에 의한다. The ubiquitin proteasome system is an important regulatory mechanism in cell growth and division, cell cycle, intracellular signaling, and apoptosis. Through this regulatory mechanism, proteins that act as substrates are degraded by the proteasome. do. In other words, multiple ubiquitin protein chains covalently bind to substrates, and these are recognized and decomposed by the 26S proteasome, which consists of 20S CP (catalytic core particle) and 19S RP (regulatory particle).

포유동물의 프로테아좀은 세 가지의 주요 탈유비퀴틴화 효소, 즉 RPN11, UCH37 및 USP14를 함유하는데, 이 중 UCH37(ubiquitin c-terminal hydrolase 37)은 20S CP(catalytic core particle)와 19S RP(regulatory particle)로 구성된 26S 프로테아좀에서 19S RP의 서브유닛 중 하나이며, UCHL5(ubiquitin carboxyl-terminal hydrolase isozyme L5) 또는 INO80R로도 알려져 있다. UCH37은 19S RP의 프로테아좀 분해에 대한 기질의 참여 전에 작용하며, C-말단의 Cys76과 Lys48 사이의 유사 펩타이드 결합을 분해하여 말단부에서 단백질이 부착된 폴리유비퀴틴 사슬을 분해하는데, 사슬들을 전체적으로 제거한다기보다는 이들을 짧게 한다. UCH37에 의한 사슬 트리밍(chain trimming)은 긴 멀티유비퀴틴 사슬과 짧은 멀티유비퀴틴 사슬 사이를 구별하는 프로테아좀의 능력을 증가시킨다. UCH37은 세포 주기의 진행, 분화, DNA 복제와 수리, 전사, 단백질 품질 관리, 면역 반응 그리고 세포 자멸사 등을 비롯한 몇몇의 과정과 관련이 있으며, 정상 조직에 비교했을 때 인간 자궁경부암 조직에서 상향 조절된다고 밝혀졌다.The mammalian proteasome contains three major deubiquitinating enzymes, RPN11, UCH37, and USP14, of which ubiquitin c-terminal hydrolase 37 (UCH37) binds the 20S catalytic core particle (CP) and the 19S RP (regulatory It is one of the subunits of 19S RP in the 26S proteasome composed of particles, and is also known as UCHL5 (ubiquitin carboxyl-terminal hydrolase isozyme L5) or INO80R. UCH37 acts before the substrate participates in the proteasomal degradation of 19S RP, and degrades the polyubiquitin chain attached to the protein at the end by cleaving the similar peptide bond between Cys76 and Lys48 at the C-terminus, removing the chains entirely. Keep them short rather than multiple. Chain trimming by UCH37 increases the ability of the proteasome to distinguish between long and short multiubiquitin chains. UCH37 is involved in several processes, including cell cycle progression, differentiation, DNA replication and repair, transcription, protein quality control, immune response, and apoptosis, and is upregulated in human cervical cancer tissue compared to normal tissue. It turns out.

유비퀴틴-프로테아좀 시스템은 여러 종류의 암, 신경 퇴화 질병, 신진 대사 장애, 바이러스성 질병, 심장 질환 그리고 노화 관련 질병 유발에 영향을 미치는 것으로 보고되고 프로테아좀 활성의 저해는 암세포의 자살과 암세포의 증식을 억제하는 것으로 알려져, 항암제로서 프로테아좀 저해제에 대한 관심과 개발이 크게 증가하고 있다. 암 치료제로 미국 FDA의 승인을 받은 20S 프로테아좀 억제제인 보르테조밉(Bortezomib)의 경우가 이러한 접근의 유효성을 검사할 수 있는 좋은 예이다. 많은 화학 물질이 UB-경로에서 효소를 대상으로 하지만, 유비스타틴(ubistatin)는 K48-결합 폴리유비퀴틴에 직접 결합함으로써 유비퀴틴과 단백질의 상호 작용을 차단하는 억제제로 확인되었다. 또한, 유비스타틴은 세포주기 성분의 프로테아좀-의존성 분해를 억제하여 세포주기의 진행을 막을 수 있음을 입증하고 있다. 그러나 유비스타틴의 세포막 비투과성은 치료제 및 세포 내 프로브를 포함하는 응용분야로의 개발에 큰 제약이 되고 있다. 이에, 상기 한계를 개선하는 유비퀴틴-경로 억제제의 개발이 여전히 요구되고 있다.The ubiquitin-proteasome system has been reported to play a role in causing several types of cancer, neurodegenerative diseases, metabolic disorders, viral diseases, heart diseases, and age-related diseases. Inhibition of proteasome activity leads to cancer cell suicide and cancer cell death. Known to inhibit the proliferation of , interest in and development of proteasome inhibitors as anticancer drugs is greatly increasing. Bortezomib, a 20S proteasome inhibitor approved by the US FDA as a cancer treatment, is a good example to test the effectiveness of this approach. Although many chemicals target enzymes in the UB-pathway, ubistatin has been identified as an inhibitor that blocks the interaction of ubiquitin with proteins by binding directly to K48-linked polyubiquitin. Additionally, it has been demonstrated that ubistatin can prevent cell cycle progression by inhibiting proteasome-dependent degradation of cell cycle components. However, ubistatin's impermeability to cell membranes is a major limitation in its development for applications including therapeutics and intracellular probes. Accordingly, the development of ubiquitin-pathway inhibitors that improve the above limitations is still required.
