| 中文名称 | 丝氨酸/苏氨酸蛋白激酶Smg1封闭多肽 |
| 英文别名 | 61E3.4; ATX; hSMG1; KIAA0421; Lambda interacting protein; Lambda/iota protein kinase C interacting protein; LIP; Phosphatidylinositol 3 kinase related kinase; Phosphatidylinositol 3 kinase related protein kinase; PI-3-kinase-related kinase SMG-1; Serine/threonine protein kinase SMG1. |
| 纯化方法 | HPLC |
| 研究领域 | Epigenetics and Nuclear Signaling > DNA / RNA > RNA Processing |
| 亚基 | Component of the SMG1C complex composed of SMG1, SMG8 and SMG9; the recruitment of SMG8 to SMG1 N-terminus induces a large conformational change in the SMG1 C-terminal head domain containing the catalytic domain. Component of the transient SURF (SMG1-UPF1-eRF1-eRF3) complex. Interacts with PRKCI. Interacts with TELO2 and TTI1. Interacts with RUVBL1 and RUVBL2. Interacts with UPF2. |
| 亚细胞定位 | Nuclear. Cytoplasm. |
| 组织特异性 | Widely expressed, with highest level in heart and skeletal muscle. Expressed in placenta, brain, lung and spleen, but not in liver. |
| 翻译后修饰 | utophosphorylated. |
| 相似性 | Belongs to the PI3/PI4-kinase family. Contains 1 FAT domain. Contains 1 FATC domain. Contains 1 HEAT repeat. Contains 1 PI3K/PI4K domain. |
| 功能 | Serine/threonine protein kinase involved in both mRNA surveillance and genotoxic stress response pathways. Recognizes the substrate consensus sequence [ST]-Q. Plays a central role in nonsense-mediated decay (NMD) of mRNAs containing premature stop codons by phosphorylating UPF1/RENT1. Recruited by release factors to stalled ribosomes together with SMG8 and SMG9 (forming the SMG1C protein kinase complex), and UPF1 to form the transient SURF (SMG1-UPF1-eRF1-eRF3) complex. In EJC-dependent NMD, the SURF complex associates with the exon junction complex (EJC) through UPF2 and allows the formation of an UPF1-UPF2-UPF3 surveillance complex which is believed to activate NMD. Also acts as a genotoxic stress-activated protein kinase that displays some functional overlap with ATM. Can phosphorylate p53/TP53 and is required for optimal p53/TP53 activation after cellular exposure to genotoxic stress. Its depletion leads to spontaneous DNA damage and increased sensitivity to ionizing radiation (IR). May activate PRKCI but not PRKCZ. |

| 背景资料 | This gene encodes a protein involved in nonsense-mediated mRNA decay (NMD) as part of the mRNA surveillance complex. The protein has kinase activity and is thought to function in NMD by phosphorylating the regulator of nonsense transcripts 1 protein. Alternatively spliced transcript variants have been described, but their full-length nature has yet to be determined. [provided by RefSeq, Mar 2013] |
