T. T. Fu, F. C. Li, Y. Zhang, J. Y. Yin, W. Q. Qiu, X. D. Li, X. G. Liu, W. W. Xin, C. Z. Wang, L. S. Yu, J. Q. Gao, Q. C. Zheng*, S. Zeng* & F. Zhu*. VARIDT 2.0: structural variability of drug transporter. Nucleic Acids Research. 50(D1): D1417-D1431 (2022). PMID: 34747471

VARIDT Provided 266 Drug Transporters (DTs) Transporting 585 FDA Approved and 246 Clinical/Preclinical Drugs for 414 Diseases

Four Aspects of Structural Variability are Provided for Each DT in VARIDT 2.0 (Graphic Illustration) :

α. Mutation-induced Spatial Variations in Folded State (MISVFS)

145 mutation-induced structures originating from 42 DTs

β. Difference among the DT Structures of Human and Model Organisms (DASHMO)

1,622 inter-species structures from 17 species covering 292 DTs

γ. Outward-facing and Inward-facing Conformations (OFAIFC)

118 conformations belonging to 59 DTs

δ. Xenobiotics-driven Alterations in 3D Complex (XEDAIC)

822 xenobiotics-regulated structures of 506 xenobiotics in complex with 57 DTs

Three Aspects of Variability Data are Provided for Each DT in VARIDT 1.0 (Graphic Illustration) :

α. Epigenetic Regulations and Genetic Polymorphisms of DTs (ERGPDT)

23,947 DNA methylations, 7,225 noncoding RNA regulations, 92 histone modifications and 1,278 genetic polymorphisms of DTs

β. Disease-, Species-, and Tissue-Specific Protein Abundances (DSTSPA)

Differential abundance profiles and downloadable data of 257 DTs in 21,781 patients/healthy individuals of 61 tissues and 108 diseases

Protein abundances of 245 DTs in 67 tissues of Homo sapiens or model organisms (Mus musculus and Rattus norvegicus)

γ. Exogenous Factors Modulating DT Activity (EFMDTA)

1,225 exogenous factors (dietary constituents, small molecular/biological drugs, natural products, etc.) modulating activity of 148 DTs

Data Standardization Facilitating Comprehensive Health Management :

1. Diseases Affected by the Drugs of Clinical Importance

All diseases were standardized using the latest version of International Classification of Diseases (ICD-11, released by the WHO)

2. Functional Family of Each Drug Transporter (DT)

Functional family of each DT was standardized using the phylogenetic classification of Transporter Classification Database (TCDB)

3. Unit of Kinetic Parameter (Km value) for Transporting Drugs

The affinity measured by Km value for the drugs transported by their corresponding DTs were unified to the unit of micromolar

4. 2D and 3D Structures of Small Molecular Drugs

The structures of the small molecular drugs transported by DTs were drawn and were standardized in the .sdf format (both 2D and 3D)

5. Crosslinking with Other Biological/Pharmaceutical Databases

UniProtKB, TCDB, dbSNP, Drugs@FDA,, ICD-11, PubChem, ChEBI, TTD, NCBI Gene, CAS Registry Number, etc.
