功能 | Keratin 18 is a type I cytokeratin. It is, together with its filament partner keratin 8, perhaps the most commonly found products of the intermediate filament gene family. They are expressed in single layer epithelial tissues of the body. Mutations in this gene have been linked to cryptogenic cirrhosis. Two transcript variants encoding the same protein have been found for this gene. Keratin 18 is often used together with keratin 8 and keratin 19 to differentiate cells of epithelial origin from hematopoietic cells in tests that enumerate circulating tumor cells in blood. | Keratin 18 是一种 I 型细胞角蛋白。它与它的纤维伴侣 keratin 8 一起,可能是中间纤维基因家族中最常见的产物。它们在身体的单层上皮组织中表达。该基因的突变与隐源性肝硬化有关。已发现该基因有两种编码相同蛋白的转录变体。Keratin 18 通常与 keratin 8 和 keratin 19 一起用于区分上皮来源的细胞和造血细胞,以检测血液中的循环肿瘤细胞。 |

| Expressed in colon, placenta, liver and very weakly in exocervix. Increased expression observed in lymph nodes of breast carcinoma | 在结肠、胎盘、肝脏中表达,在宫颈外膜中表达较弱。在乳腺癌淋巴结中观察到表达增加。 |
翻译后修饰 | Post-translational Modifications | 翻译后修饰 |
| Phosphorylation at Ser-34 increases during mitosis. Hyperphosphorylated at Ser-53 in diseased cirrhosis liver. Phosphorylation increases by IL-6. Proteolytically cleaved by caspases during epithelial cell apoptosis. Cleavage occurs at Asp-238 by either caspase-3, caspase-6 or caspase-7. O-GlcNAcylation increases solubility, and decreases stability by inducing proteasomal degradation | Ser-34 的磷酸化在有丝分裂期间增加。在肝硬化肝脏中 Ser-53 过度磷酸化。IL-6 增加磷酸化。在上皮细胞凋亡期间被 caspase 蛋白水解切割。切割发生在 Asp-238,由 caspase-3、caspase-6 或 caspase-7 介导。O-糖基化增加溶解度,并通过诱导蛋白酶体降解降低稳定性。 |
