Cytotoxic T-lymphocyte protein 4

Canonical identity and biological annotation from UniProt.

What this protein does, drawn together from its UniProt function, Gene Ontology terms and Reactome pathways.

Proteins with the strongest functional or physical association. Node size and line weight reflect STRING confidence; hover or select a partner to inspect one association.

Whether each drug engages this protein directly or through a complex, and how many other targets are recorded for it. Direct binders with few recorded targets are listed first.

Why this target matters therapeutically — disease associations, drugs in development, tractability and safety, from Open Targets.

Trials of drugs that target this protein — reached indirectly through those drugs, so a trial listed here studies the drug, not the protein.

Papers linked directly to this protein. This is the protein's own literature — descriptor-derived papers are kept separate below.

Our own weighting of the evidence behind each disease association. Human genetics and clinical evidence count for most; literature co-mention counts for little, because two entities sharing an abstract is not evidence that one drives the other.

Recent activity around this target, drawn from one canonical event stream. Every item is reached through a drug that targets this protein, so each event is news about that drug rather than about the protein directly.
