Function

Serine/threonine kinase which acts as a negative regulator of Ras-related Rap2-mediated signal transduction to control neuronal structure and AMPA receptor trafficking. Required for normal synaptic density, dendrite complexity, as well as surface AMPA receptor expression in hippocampal neurons. Can activate the JNK and MAPK14/p38 pathways and mediates stimulation of the stress-activated protein kinase MAPK14/p38 MAPK downstream of the Raf/ERK pathway. Phosphorylates: TANC1 upon stimulation by RAP2A, MBP and SMAD1. Has an essential function in negative selection of thymocytes, perhaps by coupling NCK1 to activation of JNK1. {ECO:0000269PubMed:10708748, ECO:0000269PubMed:15608642}.

Subcellular Localization

Cytoplasm {ECO:0000250}. Cell junction, synapse, postsynaptic cell membrane, postsynaptic density {ECO:0000250}. Cell projection, axon {ECO:0000250}. Cell projection, dendrite {ECO:0000250}.

Disease Associations

Tissue Specificity

Appears to be ubiquitous, expressed in all tissue types examined. Highly expressed in the brain, moderately expressed in kidney and spleen, low levels present in heart and skeletal muscle. Isoform 2 is more abundant in the brain than isoform 1. {ECO:0000269PubMed:10708748}.
