  • microsatellite query

    Hello wise people!

    I have approx 10,000 microsatellites that I obtained from some assembled dna of a non-model organism. I selected a subset of the microsatellites including 50bp of the right and left flanking sites.
    My intent is to use this subset as a query to search in sequenced dna data from a number of sample populations and see if I can find similar sequences in the different popns.

    I am trying to think of a way to do this, does anyone know of a program/software (or a combination of different programs) that can achieve this? For those who use CLC gwb, any ideas?
    I was thinking of mapping each popn to the microsatellite+flanking seqs (use the microsatellite seqs as reference), extracting a consensus sequence, then aligning that sequence back to the microsatellite seq. Is that a good way or what?
    Please help...

    Out of curiosity, can you please tell me how you identified the microsatellite regions? Any specific tool or method?

      I found a program online called phobos, that's the one I used. There is also TRF and msat commander but I haven't tried using those ones yet.

        How large is your subset that you want to investigate?

          Thanks for that. TRF seems to have been used in the 1000 genomes analysis as well.

            I am first starting with a small group ie 10 sequences, each sequence is approx 150bp (ie the left flank region + repeat motif + right flanking region). The size of one of the popns that I want to search in is approx 1.8million sequences.

              Essential Discoveries and Tools in Epitranscriptomics
              by seqadmin


              The field of epigenetics has traditionally concentrated more on DNA and how changes like methylation and phosphorylation of histones impact gene expression and regulation. However, our increased understanding of RNA modifications and their importance in cellular processes has led to a rise in epitranscriptomics research. “Epitranscriptomics brings together the concepts of epigenetics and gene expression,” explained Adrien Leger, PhD, Principal Research Scientist on Modified Bases...

              Current Approaches to Protein Sequencing
              by seqadmin


              Proteins are often described as the workhorses of the cell, and identifying their sequences is key to understanding their role in biological processes and disease. Currently, the most common technique used to determine protein sequences is mass spectrometry. While still a valuable tool, mass spectrometry faces several limitations and requires a highly experienced scientist familiar with the equipment to operate it. Additionally, other proteomic methods, like affinity assays, are constrained...
