Analyze

Symbol:

Krt20

Name:

keratin 20

RGD ID:

628646

Description:

Predicted to be a structural constituent of skin epidermis.

Predicted to be located in cytoplasm. Predicted to be active in keratin filament. Orthologous to human KRT20 (keratin 20); INTERACTS WITH 17beta-estradiol; 17beta-estradiol 3-benzoate; acetamide.

Type:

protein-coding

RefSeq Status:

VALIDATED

Previously known as:

CK-20; CK-21; cytokeratin 21; cytokeratin-20; cytokeratin-21; K20; keratin 20, type I; keratin, type I cytoskeletal 20; keratin-20; Krt21; similar to human cytokeratin 20
