The JIP group of mitogen-activated protein kinase scaffold proteins.
Activation of the c-Jun NH(2)-terminal kinase (JNK) group of mitogen-activated protein (MAP) kinases is mediated by a protein kinase cascade. This signaling mechanism may be coordinated by the interaction of components of the protein kinase cascade with scaffold proteins. The JNK-interacting protein (JIP) group of scaffold proteins selectively mediates signaling by the mixed-lineage kinase (MLK...
متن کاملThe JIP family of MAPK scaffold proteins.
The components of MAPK (mitogen-activated protein kinase) signalling pathways can assemble into complexes that are co-ordinated by regulatory proteins including scaffold proteins. There is increasing evidence that scaffold proteins (i) maintain signalling specificity and facilitate the activation of pathway components, (ii) localize pathway components to particular subcellular sites or to speci...
متن کاملIQGAP1 is a scaffold for mitogen-activated protein kinase signaling.
IQGAP1 modulates many cellular functions such as cell-cell adhesion, transcription, cytoskeletal architecture, and selected signaling pathways. We previously documented that IQGAP1 binds extracellular signal-regulated kinase (ERK) 2 and regulates growth factor-stimulated ERK activity. Here we show that MEK, the molecule immediately upstream of ERK in the Ras/mitogen-activated protein (MAP) kina...
متن کاملInactivation of mitogen-activated protein kinase signaling pathway reduces caspase-14 expression in impaired keratinocytes
Objective(s):Several investigations have revealed that caspase-14 is responsible for the epidermal differentiation and cornification, as well as the regulation of moisturizing effect. However, the precise regulation mechanism is still not clear. This study was aimed to investigate the expression of caspase-14 in filaggrin-deficient normal human epidermal keratinocytes (NHEKs) and to explore the...
متن کاملRole of the JIP4 scaffold protein in the regulation of mitogen-activated protein kinase signaling pathways.
The c-Jun NH2-terminal kinase (JNK)-interacting protein (JIP) group of scaffold proteins (JIP1, JIP2, and JIP3) can interact with components of the JNK signaling pathway and potently activate JNK. Here we describe the identification of a fourth member of the JIP family. The primary sequence of JIP4 is most closely related to that of JIP3. Like other members of the JIP family of scaffold protein...
