Summaries for SDK2 Gene

Entrez Gene Summary for SDK2 Gene

  • The protein encoded by this gene is a member of the immunoglobulin superfamily. The protein contains two immunoglobulin domains and thirteen fibronectin type III domains. Fibronectin type III domains are present in both extracellular and intracellular proteins and tandem repeats are known to contain binding sites for DNA, heparin and the cell surface. This protein, and a homologous mouse sequence, are very similar to the Drosophila sidekick gene product but the specific function of this superfamily member is not yet known. Evidence for alternative splicing at this gene locus has been observed but the full-length nature of additional variants has not yet been determined. [provided by RefSeq, Jul 2008]

GeneCards Summary for SDK2 Gene

SDK2 (Sidekick Cell Adhesion Molecule 2) is a Protein Coding gene. Diseases associated with SDK2 include Congenital Stationary Night Blindness and Joubert Syndrome 1. An important paralog of this gene is DSCAML1.

UniProtKB/Swiss-Prot for SDK2 Gene

  • Adhesion molecule that promotes lamina-specific synaptic connections in the retina and is specifically required for the formation of neuronal circuits that detect motion. 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. Promotes synaptic connectivity via homophilic interactions.
