putative conserved domain in introns

Question

[ravihansa82]

I am currently working on set of long intron sequences..once I put them in to NCBI CD-search tool(CDD) those intron sequences showed that such sequences are having putative conserved domains and the domains coming under all types hits such as specific, non-specific, superfamily and multi domain...can somebody explain me..how this is happening. because introns are not involve in protein coding...

Just because they don't code for protein doesn't mean there aren't regulatory motifs there...

[ravihansa82]

yes I agree with you..cz introns are having regulatory motifs for regulate the transcription. I am working with set of first introns right now...once I put some random sequences of first introns into the NCBI ,conserved domain data base(CDD)..resutls showed such sequences having putative conserved domain..I need to know how this happen...
