Summaries for LGSN Gene

Entrez Gene Summary for LGSN Gene

  • This gene encodes a protein with similarity to the GS I members of the glutamine synthetase superfamily. The encoded protein is referred to as a pseudo-glutamine synthetase because it has no glutamine synthesis activity and may function as a chaperone protein. This protein is localized to the lens and may be associated with cataract disease. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jan 2009]

GeneCards Summary for LGSN Gene

LGSN (Lengsin, Lens Protein With Glutamine Synthetase Domain) is a Protein Coding gene. Diseases associated with LGSN include Retinitis Pigmentosa. GO annotations related to this gene include glutamate-ammonia ligase activity.

UniProtKB/Swiss-Prot for LGSN Gene

  • May act as a component of the cytoskeleton or as a chaperone for the reorganization of intermediate filament proteins during terminal differentiation in the lens. Does not seem to have enzymatic activity (By similarity).
