JNKs

Monday 29 August 2005

Signaling mediates cellular responses to extracellular stimuli. The c-Jun NH(2)-terminal kinase (JNK) pathway exemplifies one subgroup of the mitogen-activated protein (MAP) kinases, which, besides having established functions in stress response, also contribute to development by an unknown mechanism.

JNK-bound promoters are enriched with binding motifs for the transcription factor NF-Y but not for AP-1.

NF-Y occupies these predicted sites, and overexpression of dominant-negative NF-YA reduces the JNK presence on chromatin.

MAP kinase binding and function on chromatin is a novel class of target genes during stem cell differentiation.
