MAPK8IP2

C-jun-amino-terminal kinase-interacting protein 2 is a protein or the name of the gene that encodes it.[4][5] The gene is also known as Islet-Brain-2 (IB2).

This protein is highly expressed in the brain and is almost always deleted in Phelan-McDermid syndrome (PMS). MAPK8IP2 appears to regulate the ratio of AMPA receptors to NMDA receptors at glutamate synapses,[6] and thus may be an important contributor to the intellectual dysfunction and related neurological manifestations characteristic of PMS.

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. Alternatively spliced transcript variants encoding distinct isoforms have been reported for this gene.[5]

Interactions

MAPK8IP2 has been shown to interact with MAP3K10,[4] Mitogen-activated protein kinase 9,[4] LRP2,[7][8] LRP1,[7] MAPK8IP3,[9] MAP3K12,[4] MAPK8IP1,[4] MAP2K7[4][10] and MAP3K11.[4]
