Gene

ALOX5

Organism
Mesocricetus auratus (Golden hamster)
Status
Reviewed - Annotation score: 4 out of 5- Experimental evidence at transcript leveli

Functioni

Catalyzes the first step in leukotriene biosynthesis, and thereby plays a role in inflammatory processes.

Catalytic activityi

Arachidonate + O2 = leukotriene A4 + H2O.

Cofactori

Protein has several cofactor binding sites:
  • Fe cationPROSITE-ProRule annotationNote: Binds 1 Fe cation per subunit.PROSITE-ProRule annotation
  • Ca2+By similarityNote: Binds 2 calcium ions per subunit.By similarity

Subcellular locationi

Cytoplasm PROSITE-ProRule annotation. Nucleus matrix By similarity. Nucleus membrane By similarity; Peripheral membrane protein By similarity
Note: Shuttles between cytoplasm and nucleus. Found exclusively in the nucleus, when phosphorylated on Ser-271. Calcium binding promotes translocation from the cytosol and the nuclear matrix to the nuclear envelope and membrane association (By similarity).By similarity

Post-translational modificationi

Serine phosphorylation by MAPKAPK2 is stimulated by arachidonic acid. Phosphorylation on Ser-523 by PKA has an inhibitory effect. Phosphorylation on Ser-271 prevents export from the nucleus (By similarity).By similarity

Keywords - PTMi
