General annotation (Comments)

Function

Cytochromes P450 are a group of heme-thiolate monooxygenases. In liver microsomes, this enzyme is involved in an NADPH-dependent electron transport pathway. It oxidizes a variety of structurally unrelated compounds, including steroids, fatty acids, and xenobiotics.

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.

Induction

Up-regulated by cannabidiol. Ref.3

Sequence similarities

Belongs to the cytochrome P450 family.

Ontologies

Alternative products

This entry describes 2 isoforms produced by alternative splicing. [Align] [Select]
Isoform 1 (identifier: P12791-1)

This isoform has been chosen as the 'canonical' sequence. All positional information in this entry refers to it. This is also the sequence that appears in the downloadable versions of the entry.
Isoform 2 (identifier: P12791-2)

The sequence of this isoform differs from the canonical sequence as follows:
     433-441: Missing.
