Rabbit Anti-CK10/FITC Conjugated antibody
background:
Cytokeratin 10 is a heterotetramer of two type I and two type II keratins. Cytokeratin 10 is generally associated with keratin 1. It is seen in all suprabasal cell layers including stratum corneum. A number of alleles are known that mainly differ in the Gly-rich region (positions 490-560). Defects in cytokeratin 10 are a cause of epidermolytic hyperkeratosis (EHK), also known as bullous congenital ichthyosiform erythroderma (BCIE) or bullous erythroderma ichthyosiformis congenita of Brocq. EHK is an hereditary skin disorder characterized by blistering and a marked thickening of the stratum corneum. At birth, affected individuals usually present with redness, blisters and superficial erosions due to cytolysis. Within a few weeks, the erythroderma and blister formation diminish and hyperkeratoses develop. Transmission is autosomal dominant, but most cases are sporadic. Defects in cytokeratin 10 are also a cause of annular epidermolytic ichthyosis (AEI), also known as cyclic ichthyosis with epidermolytic hyperkeratosis. AEI resembles clinical and histologic features of both epidermolytic hyperkeratosis and ichthyosis bullosa of Siemens.
Subunit:
Heterotetramer of two type I and two type II keratins. keratin-10 is generally associated with keratin-1.
Tissue Specificity:
Seen in all suprabasal cell layers including stratum corneum.
DISEASE:
Epidermolytic hyperkeratosis (EHK) [MIM:22800]: An autosomal dominant skin disorder characterized by widespread blistering and an ichthyotic erythroderma at birth that persist into adulthood. Histologically there is a diffuse epidermolytic degeneration in the lower spinous layer of the epidermis. Within a few weeks from birth, erythroderma and blister formation diminish and hyperkeratoses develop. Note=The disease is caused by mutations affecting the gene represented in this entry.
Ichthyosis annular epidermolytic (AEI) [MIM:607602]: A skin disorder resembling bullous congenital ichthyosiform erythroderma. Affected individuals present with bullous ichthyosis in early childhood and hyperkeratotic lichenified plaques in the flexural areas and extensor surfaces at later ages. The feature that distinguishes AEI from BCIE is dramatic episodes of flares of annular polycyclic plaques with scale, which coalesce to involve most of the body surface and can persist for several weeks or even months. Note=The disease is caused by mutations affecting the gene represented in this entry.
Erythroderma, ichthyosiform, congenital reticular (CRIE) [MIM:609165]: A rare skin condition characterized by slowly enlarging islands of normal skin surrounded by erythematous ichthyotic patches in a reticulated pattern. The condition starts in infancy as a lamellar ichthyosis, with small islands of normal skin resembling confetti appearing in late childhood and at puberty. Histopathologic findings include band-like parakeratosis, psoriasiform acanthosis, and vacuolization of keratinocytes with binucleated cells in the upper epidermis, sometimes associated with amyloid deposition in the dermis. Ultrastructural abnormalities include perinuclear shells formed from a network of fine filaments in the upper epidermis. Note=The disease is caused by mutations affecting the gene represented in this entry.
Similarity:
Belongs to the intermediate filament family.

细胞角蛋白是形成上皮细胞细胞骨架中间纤维的一类结构相关蛋白。CK10属于I型角蛋白，常常与CK1一起存在。缺失CK10与表皮松解性角化症（EHK）以及表皮松解性鳞癣病（AEI）密切相关。主要标记上皮的基底上层和颗粒细胞层细胞，同时CK10表达与细胞的分化程度呈正比，高分化者常阳性更强，故常用于鳞状细胞癌的诊断。
