Summary: Enables kinesin binding activity. Involved in several processes, including behavioral fear response; excitatory postsynaptic potential; and regulation of neurotransmitter receptor activity. Acts upstream of or within JNK cascade. Located in cytoplasm; neuronal cell body; and postsynaptic density. Is expressed in several structures, including alimentary system; genitourinary system; nervous system; sensory organ; and skeleton. Orthologous to human MAPK8IP2 (mitogen-activated protein kinase 8 interacting protein 2). [provided by Alliance of Genome Resources, Apr 2022]

What's a GeneRIF?

Data demonstrate that JIP-2 and -2 proteins can influence insulin-stimulated signal transduction mediated by insulin receptor substrate proteins.
Title: Signal transduction cross talk mediated by Jun N-terminal kinase-interacting protein and insulin receptor substrate scaffold protein complexes.
JIP scaffold proteins are critically required for normal NMDA receptor function.
Title: Requirement of JIP scaffold proteins for NMDA-mediated signal transduction.
there is a signaling module in which IB2 scaffolds a MLK3/MKK/p38delta kinase cascade.
Title: Fibroblast growth factor homologous factors and the islet brain-2 scaffold protein regulate activation of a stress-activated protein kinase.
JIP2 does not influence the processing of APP, although it is known that both JIP1b and JIP2 equally regulate the JNK signaling cascade

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
