4 Copyright OpenHelix. No use or reproduction without express written consent4 Introduction Suite of Motif-based Sequence Analysis Tools Submit A Job

5 Copyright OpenHelix. No use or reproduction without express written consent5 What is a Motif? a pattern found repeatedly in DNA or protein sequences that may have biological significance. Frequently found motif: Slight differences in a motif can have important implications for function Zinc finger motif DNA binding C2H2 type RNA binding C2H2, CCHC and CCCH Protein binding LIM, MYND,RING and PHD

No use or reproduction without express written consent6 ENCODE Project Current focus of human genome research is to find and catalog all the functional elements in the human genome sequence One type of important functional elements in human genome are motifs Ability to “discover” motifs an important component of ENCODE project
