JNK is a novel regulator of intercellular adhesion

Tissue Barriers. 2013 Dec 1;1(5):e26845. doi: 10.4161/tisb.26845. Epub 2013 Oct 17.

Abstract

c-Jun N-terminal Kinase (JNK) is a family of protein kinases, which are activated by stress stimuli such as inflammation, heat stress and osmotic stress, and regulate diverse cellular processes including proliferation, survival and apoptosis. In this review, we focus on a recently discovered function of JNK as a regulator of intercellular adhesion. We summarize the existing knowledge regarding the role of JNK during the formation of cell-cell junctions. The potential mechanisms and implications for processes requiring dynamic formation and dissolution of cell-cell junctions including wound healing, migration, cancer metastasis and stem cell differentiation are also discussed.

Keywords: JNK; adherens junction; cell-cell adhesion; intercellular signaling; substrate stiffness.
