Protein attributes

Sequence length	678 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	This enzyme is required for electron transfer from NADP to cytochrome P450 in microsomes. It can also provide electron transfer to heme oxygenase and cytochrome B5.
Catalytic activity	NADPH + n oxidized hemoprotein = NADP+ + n reduced hemoprotein.
Cofactor	FAD. FMN.
Subcellular location	Endoplasmic reticulum membrane; Peripheral membrane protein. Note: Anchored to the ER membrane by its N-terminal hydrophobic region.
Sequence similarities	In the C-terminal section; belongs to the flavoprotein pyridine nucleotide cytochrome reductase family. Contains 1 FAD-binding FR-type domain. Contains 1 flavodoxin-like domain.
