产品介绍background:
Cytokeratins are a subfamily of intermediate filament proteins and are characterized by a remarkable biochemical diversity, represented in human epithelial tissues by at least 20 different polypeptides. They range in molecular weight between 40 kDa and 68 kDa and isoelectric pH between 4.9 – 7.8. The individual human cytokeratins are designated 1 to 20. The various epithelia in the human body usually express cytokeratins which are not only characteristic of the type of epithelium, but also related to the degree of maturation or differentiation within an epithelium. Cytokeratin subtype expression patterns are used to an increasing extent in the distinction of different types of epithelial malignancies. The cytokeratin antibodies are not only of assistance in the differential diagnosis of tumors using immunohistochemistry on tissue sections, but are also a useful tool in cytopathology and flow cytometric assays.

Function:
Blocks interferon-dependent interphase and stimulates DNA synthesis in cells. Involved in the translational regulation of the human papillomavirus type 16 E7 mRNA (HPV16 E7).

CK7,细胞角蛋白7抗体Subunit:
Heterotetramer of two type I and two type II keratins. Interacts with eukaryotic translation initiator factor 3 (eIF3) subunit EIF3S10 and with HPV16 E7.

Subcellular Location:
Cytoplasm.

Tissue Specificity:
Expressed in cultured epidermal, bronchial and mesothelial cells but absent in colon, ectocervix and liver. Observed throughout the glandular cells in the junction between stomach and esophagus but is absent in the esophagus.

Post-translational modifications:
Arg-20 is dimethylated, probably to asymmetric dimethylarginine.

Similarity:
Belongs to the intermediate filament family.

Gene ID:
3855

结构蛋白（Structural Proteins）
CK-7是一种 54KDa 的中间丝蛋白，存在于大多数正常组织的腺上皮和移行上皮细胞中。 该抗体与多种良/恶性上皮性肿瘤反应。腺癌中的卵巢、乳腺、肺的腺癌呈阳性反应，而胃肠道的腺癌阴性。移行细胞肿瘤、前列腺癌也呈阳性反应。通常认为 CK7是腺癌和移行上皮细胞癌的比较特异性的标志。
