Oxoglutarate/iron-dependent oxygenase, C-terminal degradation domain (IPR019601)
Short name: Oxoglutarate/Fe-dep_Oase_C
This entry represents the C-terminal degradation domain of oxoglutarate and iron-dependent oxygenase (Ofd1), the domain being conserved from yeasts to humans. Ofd1 is a prolyl 4-hydroxylase-like 2-oxoglutarate-Fe(II) dioxygenase that accelerates the degradation of Sre1N (the N-terminal transcription factor domain of Sre1) in the presence of oxygen [PMID: 19158663]. Yeast Sre1 is the orthologue of mammalian sterol regulatory element binding protein (SREBP), and it responds to changes in oxygen-dependent sterol synthesis as an indirect measure of oxygen availability. However, unlike the prolyl 4-hydroxylases that regulate mammalian hypoxia-inducible factor, Ofd1 uses multiple domains to regulate Sre1N degradation by oxygen; the Ofd1 N-terminal dioxygenase domain is required for oxygen sensing and this Ofd1 C-terminal domain accelerates Sre1N degradation in yeasts [PMID: 18418381].
