Ask REGgie: Locating biochemical data in CAS REGISTRYSM

Ask Reggie - Question

Q:  How can I find biochemistry-related information on sequences in REGISTRY?

A:  REGISTRY includes experimental property tags to help you locate biochemical data, including information on genetic polymorphisms and drug targets in the literature.

The overlap of chemistry and the life sciences continues to grow in both size and significance.  The content of CAS REGISTRY reflects this dynamic, and the database includes a significant amount of valuable biochemical and genetic data.

As the sequencing of many prokaryotic and eukaryotic genomes is completed, and the encoded proteins are identified and characterized, DNA, RNA, and protein sequences are assigned CAS Registry Numbers.


REGISTRY records and experimental property data

REGISTRY records include experimental property data and links to other STN databases that contain references to the sequence.  The EPROP display format in REGISTRY allows you to display all of the available experimental property data.

Example of a REGISTRY record for a sequence.

Experimental property tags

To elucidate a protein's biological function(s), it may be important to know its localization within the cell, interactions with other proteins, linkage to phenotypic traits, and/or post-translational modification(s).

To organize this data and help compile it in a single location, new experimental property tags in REGISTRY refer to the genetic, biochemical, and molecular data associated with a given sequence or substance.  These include:

  • Allele frequency and heterozygosity
  • Disease-related mutations
  • Drug targets
  • Functional sites
  • Genetic mapping
  • Genetic polymorphism
  • Human disease-related mutations
  • Non-human disease-related mutations
  • Plant disease-related mutations
  • Post-translational protein modifications
  • Subcellular localization

To display biological and chemical property tags, you can use the ETAG field code.  If a tag appears in the Experimental Property Tags (ETAG) table, information pertaining to that property is available for the given substance.

 

To simplify finding records related to a property tag, reference information is given directly below the Experimental Property Tag table.  When you click the link in the reference, the record of interest is displayed.  For example, clicking the CAPLUS link at the end of reference 1 automatically accesses the CAplusSM database and displays the record containing allele frequency and heterozygosity data.

TITLE:             Estimation of warfarin maintenance dose

ABSTRACT:
CYP2C9 polymorphisms are assocd. with decreased S-warfarin clearance
and lower maintenance dosage.  Decreased expression of VKORC1 resulting
from the -1639G>A substitution has also been implicated in lower warfarin
dose requirements.  We investigated the addnl. contribution of this polymorphism

Displaying all available property tags

Information related to a property is often found in more than one reference.  By default, the ETAG display format lists only one reference per property tag.  However, you can display the full list of references by using the MAX or ETAGFULL display format.

Multidisciplinary coverage within REGISTRY

The rate at which prokaryotic and eukaryotic genomes are being sequenced, and the encoded proteins are being identified and characterized, continues to increase.  As vast amounts of new inormation are generated, databases play an increasingly vital role as central resources for organizing and storing this data.

With the recent introduction of genetic and biological property tags, REGISTRY reflects the dynamic developments in chemistry, biology, and other sciences.  Evolving in response to the overlap of scientific disciplines positions REGISTRY as a valuable resource not only for chemists but for all members of the scientific community.
