Rat Cytochrome P450s

Note on Jan. 24, 2007 I started this page. Completed April 27, 2007

The rat genome has 88 P450 genes and 69 P450 pseudogenes.

This table has over 850 links to sequence and map data

I include seven gene cluster maps that show human, mouse and rat compared (red links in the first column).

These map links are also included in the human master table. These maps are further described in:

Comparison of cytochrome P450 (CYP) genes from the mouse and human genomes

Pharmacogenetics 14, 1-18 2004

The maps and the nucleotide numbering in the protein sequence links were based

on an earlier version of the rat genome assembly, so the numbers are a little

different from the new UCSC browser nucleotide numbering.

Current UCSC links are based on the Nov. 2004 assembly.

My first links to UCSC were unstable. I have now replaced those links with a

stable format: http://genome.ucsc.edu/cgi-bin/hgTracks?org=rat&db=rn4&position=chr8%3A61350064-61538088

These links should be permanent.

The Entrez Gene links have extensive data and links for intact sequences and some pseudogenes.

For a complete set of rat P450 sequences including pseudogenes go to the FASTA file

All rat P450 genes and all P450 pseudogenes will be included in this table.

CYP names in column 1 are linked to their protein sequences, including the pseudogenes.

X at the end of a CYP name means that name has been discontinued and replaced by a new name

Pseudogenes are named using suffixes to specify the four types of pseudogenes defined as:

P is a full length or near full length pseudogene, it may be near or far from other P450s.

-ps is equivalent to P, but it is required nomenclature for mouse and rat full length pseudogenes.

-de stands for detritus exons (found near other full length genes).

-se stands for solo exons, one or a few exons found distant from a P450 gene.

-ie stands for internal exons, duplicate exons found inside some P450 genes.
