Summaries for ASNS Gene

Entrez Gene Summary for ASNS Gene

  • The protein encoded by this gene is involved in the synthesis of asparagine. This gene complements a mutation in the temperature-sensitive hamster mutant ts11, which blocks progression through the G1 phase of the cell cycle at nonpermissive temperature. Alternatively spliced transcript variants have been described for this gene. [provided by RefSeq, May 2010]

GeneCards Summary for ASNS Gene

ASNS (Asparagine Synthetase (Glutamine-Hydrolyzing)) is a Protein Coding gene. Diseases associated with ASNS include Asparagine Synthetase Deficiency and Congenital Microcephaly-Severe Encephalopathy-Progressive Cerebral Atrophy Syndrome. Among its related pathways are Amino acid synthesis and interconversion (transamination) and Metabolism. GO annotations related to this gene include protein homodimerization activity and asparagine synthase (glutamine-hydrolyzing) activity.
