The present invention relates to isolated MEKK proteins, nucleic acid molecules having sequences that encode such proteins, and antibodies raised against such proteins. The present invention also includes methods to use such proteins to regulate signal transduction in a cell. The present invention also includes therapeutic compositions comprising such proteins or nucleic acid molecules that encode such proteins and their use to treat animals having medical disorders including cancer, inflammation, neurological disorders, autoimmune diseases, allergic reactions, and hormone-related diseases. When MEKK is expressed, it phosphorylates and activates MKKs 1-4 (also referred to as MEK-1, MEK-2 and JNKK1 and JNKK2).

A invenção atual relaciona-se às proteínas isoladas de MEKK, às moléculas do ácido nucleic que têm as seqüências que codificam tais proteínas, e aos antibodies levantados de encontro a tais proteínas. A invenção atual inclui também métodos para usar tais proteínas regular o transduction do sinal em uma pilha. A invenção atual incluem também as composições therapeutic que compreendem tais proteínas ou as moléculas do ácido nucleic que codificam tais proteínas e seu uso tratar os animais que têm disorders médicos including o cancer, o inflammation, disorders neurological, doenças autoimmune, reações allergic, e doenças hormone-relacionadas. Quando MEKK é expressado, phosphorylates e ativa MKKs 1-4 (consultado também como a MEK-1, MEK-2 e JNKK1 e JNKK2).
