DESCRIPTION

Also known as SDK2_MOUSE, Sdk2, Kiaa1514. Adhesion molecule that promotes lamina-specific synaptic connections in the retina and is specifically required for the formation of neuronal circuits that detect motion (PubMed:26287463). Acts by promoting formation of synapses between two specific retinal cell types: the retinal ganglion cells W3B-RGCs and the excitatory amacrine cells VG3-ACs. Formation of synapses between these two cells plays a key role in detection of motion (PubMed:26287463). Promotes synaptic connectivity via homophilic interactions (PubMed:26287463). Homodimer; mediates homophilic interactions to promote cell adhesion (PubMed:15703275, PubMed:26287463). Interacts (via PDZ-binding motif) with MAGI1, MAGI2, DLG2, DLG3 and DLG4 (PubMed:20219992).
