The Blocks WWW server provides tools to search DNA and protein queries against the Blocks database of multiple alignments, which represent conserved protein regions.
One-Block CYRCA is a program for identifying blocks (local ungapped profiles of the most conserved regions of protein families and domains) in a multiple sequence alignment based on the LAMA and CYRCA block-to-block alignment methods.
taveRNA hosts three RNA web services: alteRNA, inteRNA and pRuNA. alteRNA is an alternative to many RNA folding methods. inteRNA predicts the joint secondary structure of two RNA sequences. pRuNA is an database pruning method which given a query RNA returns only a few ncRNAs as potential regulators.
