Protein attributes

Sequence length	502 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	This enzyme metabolizes arachidonic acid predominantly via a NADPH-dependent olefin epoxidation to all four regioisomeric cis-epoxyeicosatrienoic acids. One of the predominant enzymes responsible for the epoxidation of endogenous cardiac arachidonic acid pools.
Catalytic activity	RH + reduced flavoprotein + O2 = ROH + oxidized flavoprotein + H2O.
Cofactor	Heme group By similarity.
Subcellular location	Endoplasmic reticulum membrane; Peripheral membrane protein. Microsome membrane; Peripheral membrane protein.
Tissue specificity	Highly expressed in heart, present at lower levels in liver, ileum, jejunum, colon, and kidney.
Sequence similarities	Belongs to the cytochrome P450 family.
