La MAP quinasa 14 (MAPK14) es una enzima codificada en humanos por el gen mapk14.[1]
La MAPK14 pertenece a la familia de las MAP quinasas. Las MAP quinasas actúan como punto de integración de múltiples señales bioquímicas, y están implicadas en una amplia variedad de procesos celulares tales como proliferación celular, diferenciación celular, regulación de la transcripción y desarrollo. La MAPK14 es activada por diversos estímulos ambientales relacionados con el estrés y por citoquinas proinflamatorias. Dicha activación requiere la fosforilación llevada a cabo por MAP quinasa quinasas (MKKs), o bien su propia autofosforilación llevada a cabo por la interacción del complejo MAP3K7IP1/TAB1 con MAPK14. Los sustratos de esta quinasa incluyen diversas proteínas o factores de transcripción como ATF2, MEF2C, MAX, el regulador del ciclo celular CDC25B y el supresor tumoral p53, lo que sugiere un papel de esta quinasa en regulación del ciclo celular y la transcripción, así como en respuesta a estrés genotóxico. Se han descrito cuatro variantes transcripcionales de este gen, que codifican diversas isoformas de la quinasa.[2]
