Generated using BioBTree cross-database mapping
Last updated: March 2026
I’ve compiled a comprehensive cross-database identifier and functional mapping reference for human CCND1 (Cyclin D1).
Key highlights from this reference:
- Gene location: Chromosome 11q13.3 (69,641,143-69,654,474, + strand)
- Primary identifiers: HGNC:1582, ENSG00000110092, Entrez 595, OMIM 168461
- Protein: 295 amino acids (33.7 kDa), UniProt P24385 with 6 InterPro domains
- Structures: 11 PDB structures (10 X-ray, 1 Cryo-EM), primarily complexed with CDK4/CDK6
- Clinical relevance:
- 4 FDA-approved CDK4/6 inhibitors target the CCND1-CDK4/6 complex (palbociclib, ribociclib, abemaciclib, trilaciclib)
- Associated with multiple myeloma, mantle cell lymphoma, and breast cancer
- 45 GWAS associations including breast cancer (p=4×10⁻⁹⁵)
- Regulation: Over 100 transcription factors regulate CCND1, including MYC, β-catenin, ESR1, E2F1, and STAT3
- Expression: Ubiquitously expressed with highest levels in proliferative epithelia (endometrium, skin, esophagus)
- Variant predictions: 1,940 AlphaMissense predictions and 854+ SpliceAI predictions available for clinical interpretation
