Contactin-associated protein 1 (IPR028872)

Short name: Caspr1

Family relationships

None.

Description

Contactin-associated protein 1 (also known as paranodin or caspr1) has a key role in the formation of the paranodal junctions and is required for normal saltatory conduction [PMID: 11395000]. It seems to demarcate the paranodal region of the axo-glial junction. In association with contactin, it may have a role in the signaling between axons and myelinating glial cells [PMID: 9118959, PMID: 9292722, PMID: 9396755, PMID: 9786343]. It also plays a role in regulating of the trafficking of AMPA receptors to synapses [PMID: 22223644].
