Welcome to PolyA_DB, a web resource for mRNA polyadenylation sites

 


Poly(A) site databases

PolyA_DB 1

ENTER

PolyA_DB version 1 contains human and mouse poly(A) sites that are mapped by cDNA/EST sequences.

PolyA_DB 2

ENTER

PolyA_DB version 2 contains poly(A) sites in human, mouse, rat, chicken and zebrafish that are mapped by cDNA/EST and Trace sequences. Sequence alignments between orthologous sites are available.

Poly(A) site prediction tools

PolyA_SVM

ENTER

PolyA_SVM predicts poly(A) sites using 15 cis elements identified for human poly(A) sites.
