Abstract:
Mutations in von Hippel-Lindau tumor suppressor protein (pVHL) predispose to develop tumors affecting specific target organs, such as the retina, epididymis, adrenal glands, pancreas and kidneys. Currently, more than 400 pVHL interacting proteins are either described in the literature or predicted in public databases. This data is scattered among several different sources, slowing down the comprehension of pVHL's biological role. Here we present VHLdb, a novel database collecting available interaction and mutation data on pVHL to provide novel integrated annotations. In VHLdb, pVHL interactors are organized according to two annotation levels, manual and automatic. Mutation data are easily accessible and a novel visualization tool has been implemented. A user-friendly feedback function to improve database content through community-driven curation is also provided. VHLdb presently contains 478 interactors, of which 117 have been manually curated, and 1,074 mutations. This makes it the largest available database for pVHL-related information. VHLdb is available from URL: http://vhldb.bio.unipd.it/.
Insights
The von Hippel-Lindau tumor suppressor protein (pVHL) database (VHLdb) consolidates scattered pVHL interaction and mutation data. This resource aids in understanding pVHL
Area of Science:
- Molecular Biology
- Genetics
- Bioinformatics
Background:
- Mutations in the von Hippel-Lindau tumor suppressor protein (pVHL) are linked to various tumors, including those in the retina, kidney, and adrenal glands.
- Existing information on pVHL interactors and mutations is fragmented across multiple sources, hindering comprehensive analysis.
Purpose of the Study:
- To introduce VHLdb, a novel, integrated database for pVHL interaction and mutation data.
- To facilitate a deeper understanding of the biological roles of pVHL.
Main Methods:
- Collected and organized pVHL interacting protein data into manual and automatic annotation levels.
- Integrated mutation data with a novel visualization tool.
- Implemented a community-driven curation feedback function.
Main Results:
- VHLdb currently houses 478 pVHL interactors, with 117 manually curated.
- The database includes 1,074 documented mutations.
- VHLdb is the most extensive repository for pVHL-related information.
Conclusions:
- VHLdb provides a centralized and comprehensive resource for pVHL research.
- The database enhances accessibility to crucial interaction and mutation data, supporting future investigations into pVHL's function and associated diseases.
