Gene: Krt8 (keratin 8) Rattus norvegicus
Symbol: Krt8
Name: keratin 8
RGD ID: 2984
Description: Predicted to enable scaffold protein binding activity. Predicted to be a structural constituent of skin epidermis. Involved in response to hydrostatic pressure and sarcomere organization. Located in keratin filament; myofibril; and sarcolemma. Part of dystrophin-associated glycoprotein complex. Human ortholog(s) of this gene implicated in liver cirrhosis. Orthologous to human KRT8 (keratin 8); INTERACTS WITH (+)-schisandrin B; 1,1,1-Trichloro-2-(o-chlorophenyl)-2-(p-chlorophenyl)ethane; 1-naphthyl isothiocyanate.
Type: protein-coding
Previously known as: CK-8; CYKER; cytokeratin endo A; cytokeratin-8; K8; keratin 8, type II; keratin complex 2, basic, gene 8; keratin, type II cytoskeletal 8; keratin-8; Krt2-8; type-II keratin Kb8
