Summaries for IL4I1 Gene

Entrez Gene Summary for IL4I1 Gene

  • This gene encodes a protein with limited similarity to L-amino acid oxidase which contains the conserved amino acids thought to be involved in catalysis and binding of flavin adenine dinucleotide (FAD) cofactor. The expression of this gene can be induced by interleukin 4 in B cells, however, expression of transcripts containing the first two exons of the upstream gene is found in other cell types. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Apr 2012]

GeneCards Summary for IL4I1 Gene

IL4I1 (Interleukin 4 Induced 1) is a Protein Coding gene. Diseases associated with IL4I1 include Striatonigral Degeneration, Infantile and Posterior Myocardial Infarction. Among its related pathways are Histidine, lysine, phenylalanine, tyrosine, proline and tryptophan catabolism and Metabolism. Gene Ontology (GO) annotations related to this gene include oxidoreductase activity and L-amino-acid oxidase activity.

UniProtKB/Swiss-Prot for IL4I1 Gene

  • Lysosomal L-amino-acid oxidase with highest specific activity with phenylalanine. May play a role in lysosomal antigen processing and presentation (By similarity).
