Kynureninase (KYNU)

Target (abbrv.) KYNU
Target (full name) Kynureninase
Somalogic ID (Sequence ID) SL013969 (4559-64_2)
Entrez Gene Symbol KYNU
UniProt ID Q16719
UniProt Comment
  • Catalyzes the cleavage of L-kynurenine (L-Kyn) and L-3-hydroxykynurenine (L-3OHKyn) into anthranilic acid (AA) and 3-hydroxyanthranilic acid (3-OHAA), respectively. Has a preference for the L-3-hydroxy form. Also has cysteine-conjugate-beta-lyase activity.

All locus annotations are based on the sentinel SNP (rs9013) and 27 proxy variant(s) that is/are in linkage disequilibrium r2 ≥ 0.8. Linkage disequilibrium is based on data from the 1000 Genomes Project, phase 3 version 5, European population and was retrieved using SNiPA's Block Annotation feature.
