| 产品编号 | bs-9249P |
| 英文名称 | RNF123 Antibody Blocking Peptide |
| 中文名称 | 环指蛋白123封闭多肽 |
| 英文别名 | E3 ubiquitin protein ligase RNF123; Kip1 ubiquitination promoting complex protein 1; KPC 1; KPC1; Ring finger protein 123; RNF 123; Ubiquitin ligase; |
| 纯化方法 | HPLC |
| 研究领域 | Cell Biology > Proteolysis / Ubiquitin > Proteasome / Ubiquitin > Ubiquitin E3 Enzymes > RING Finger E3 Ligase |
| 亚基 | Component of the KPC complex composed of RNF123/KPC1 and UBAC1/KPC2. Interacts with UBAC1 and CDKN1B via its N-terminal domain. |
| 亚细胞定位 | Cytoplasmic |
| 翻译后修饰 | Ubiquitinated, leading to its degradation. Deubiquitinated by USP19, thereby stimulating CDKN1B ubiquitin-dependent degradation (By similarity). |
| 相似性 | Contains 1 B30.2/SPRY domain. Contains 1 RING-type zinc finger. |
| 功能 | Catalytic subunit of the KPC complex that acts as E3 ubiquitin-protein ligase. Required for poly-ubiquitination and proteasome-mediated degradation of CDKN1B during G1 phase of the cell cycle. |
| 保存条件 | Shipped at 4℃. Stored at -20℃ for one year. Avoid repeated freeze/thaw cycles. |
| 注意事项 | This product as supplied is intended for research use only, not for use in human, therapeutic or diagnostic applications. |
| 背景资料 | The RING-type zinc finger motif is present in a number of viral and eukaryotic proteins and is made of a conserved cysteine-rich domain that is able to bind two zinc atoms. Proteins that contain this conserved domain are generally involved in protein-protein interactions and protein-DNA interactions. RNF123 (RING finger protein 123), also known as KPC1 (Kip1 (p27) ubiquitination-promoting complex protein 1) or FP1477, contains one RING-type zinc finger domain and one SPRY domain. Localizing to the cytoplasm, RNF123 functions as the catalytic component of the KPC complex that acts as an E3 ubiquitin-protein ligase. Specifically, RNF123 is essential for the ubiquitination and subsequent degradation of p27 during the cell cycle G1 phase. Via its N-terminus, RNF123 is known to interact with GBDR1 (another component of the KPC) and p27 (a cyclin-dependent kinase inhibitor). Due to alternative splicing events, two isoforms exist for RNF123. |
