Review-ready Target Rationale

Why Cyclin-dependent kinase 4/cyclin D1 matters

As of 2026-09-13

Cyclin-dependent kinase 4/cyclin D1 is reviewed as Cyclin-dependent kinase 4 (UniProt P11802); Cyclin-dependent kinase 4/cyclin D1 shows approved-linked disease relevance led by breast cancer. 5 more disease programs remain visible in the same review block.; 1 linked drug keep this evidence frame grounded.; the current evidence base includes 6 approved drugs, 2711 compounds, and 393 assays, with lead potency reaching pChEMBL 10.3.

Protein context

Cyclin-dependent kinase 4

Cyclin-dependent kinase 4 Sequence length is 303 aa.

Review this target as Cyclin-dependent kinase 4/cyclin D1, mapped to UniProt P11802. ChEMBL maps the protein component as Cyclin-dependent kinase 4. Sequence length is 303 aa.

Disease context

breast cancer

Cyclin-dependent kinase 4/cyclin D1 shows approved-linked disease relevance led by breast cancer. 5 more disease programs remain visible in the same review block. 1 linked drug keep the rationale reviewable. 5 additional disease programs remain visible in the same card. Linked drugs include PALBOCICLIB.

Start review with breast cancer because it currently carries approved-linked support. Linked drugs include PALBOCICLIB. This disease block keeps the Open Targets-ready contract explicit while current evidence comes from ChEMBL mechanism and indication mappings.
