FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] The protein encoded by this gene is closely related to MAPK8IP1/IB1/JIP-1, a scaffold protein that is involved in the c-Jun amino-terminal kinase signaling pathway. This protein is expressed in brain and pancreatic cells. It has been shown to interact with, and regulate the activity of MAPK8/JNK1, and MAP2K7/MKK7 kinases. This protein thus is thought to function as a regulator of signal transduction by protein kinase cascade in brain and pancreatic beta-cells. [provided by RefSeq, Feb 2014]
PHENOTYPE: Mice homozygous for a null allele are smaller in size and exhibit male infertility. Mice homozygous for a different knock-out allele exhibit behavioral and cerebellar transmission deficits. [provided by MGI curators]
