Matched no rule. Shown as-is rather than assigned a class by guesswork. Values below are reported as measured; because this is not a molecular target, they are not treated as affinities anywhere on this site.

What this target is
Its function as UniProt states it, where in a cell the protein is found, and which cell types and tissues transcribe its gene.
Cytochrome b5
Cytochrome b5 is a membrane-bound hemoprotein functioning as an electron carrier for several membrane-bound oxygenases
Quoted from UniProt’s FUNCTION annotation for P00167 (reviewed).
What it acts with
STRING’s highest-confidence human functional partners. The combined score mixes several kinds of evidence, so each channel is shown separately — a partner supported by experiment is a different claim from one supported only by text mining, and for a receptor this is where its coupling appears as evidence rather than as assertion.

Expression by cell type
Single cell type RNA, the 6 highest of those the Human Protein Atlas reports for this gene. Transcript, not protein, and a cell type rather than a tissue.
- Hepatocytes3,986.6 nCPM
- Alveolar cells type 22,211.1 nCPM
- Transitional alveolar cells1,918.9 nCPM
- Enterocytes1,661 nCPM
- Breast lactating cells1,374 nCPM
- Urothelial cells1,103.3 nCPM
Expression by tissue
The tissues this gene is enriched in, by consensus RNA. A tissue absent from this list is one the Atlas does not call specific for this gene, which is not the same as absent from it.
