UniProtKB - P27119 (DCOR_MUSPA)
Protein
Ornithine decarboxylase
Gene
Odc1
Organism
Mus pahari (Gairdner's shrew-mouse) (Coelomys pahari)
Status
Functioni
Catalyzes the first and rate-limiting step of polyamine biosynthesis that converts ornithine into putrescine, which is the precursor for the polyamines, spermidine and spermine. Polyamines are essential for cell proliferation and are implicated in cellular processes, ranging from DNA replication to apoptosis.By similarity
Catalytic activityi
- EC:4.1.1.17By similarity
Cofactori
pyridoxal 5'-phosphateBy similarity
Activity regulationi
Inhibited by antizymes (AZs) OAZ1, OAZ2 and OAZ3 in response to polyamine levels. AZs inhibit the assembly of the functional homodimer by binding to ODC monomers. Additionally, OAZ1 targets ODC monomers for ubiquitin-independent proteolytic destruction by the 26S proteasome.By similarity
