The PAZAR database of gene regulatory information coupled to the ORCA toolkit for the study of regulatory sequences

Nucleic Acids Res. 2009 Jan;37(Database issue):D54-60. doi: 10.1093/nar/gkn783. Epub 2008 Oct 29.


The PAZAR database unites independently created and maintained data collections of transcription factor and regulatory sequence annotation. The flexible PAZAR schema permits the representation of diverse information derived from experiments ranging from biochemical protein-DNA binding to cellular reporter gene assays. Data collections can be made available to the public, or restricted to specific system users. The data 'boutiques' within the shopping-mall-inspired system facilitate the analysis of genomics data and the creation of predictive models of gene regulation. Since its initial release, PAZAR has grown in terms of data, features and through the addition of an associated package of software tools called the ORCA toolkit (ORCAtk). ORCAtk allows users to rapidly develop analyses based on the information stored in the PAZAR system. PAZAR is available at ORCAtk can be accessed through convenient buttons located in the PAZAR pages or via our website at
