Database Description

GRSDB: ‘G’-Rich Sequences DataBase contains information on composition and distribution of putative Quadruplex forming 'G'-Rich Sequences (QGRS) in the alternatively processed (alternatively spliced or alternatively polyadenylated) mammalian pre-mRNA sequences. The data stored in the GRSDB is based on computational analysis of genomic nucleotide sequences obtained from fully annotated GenBank/RefSeq entries that provide alternative processing information. In addition to providing data on composition and locations of QGRS relative to the processing sites in the pre-mRNA sequence, GRSDB features visual comparison of QGRS distribution patterns among all the alternative RNA products of a gene with the help of dynamically generated graphics. . GRSDB can be accessed at


This project was funded in part by grants from the Provost Office and TLTR (The Teaching, Learning and Technology Roundtable) of Ramapo College of New Jersey.
