Hi, I am trying to understand the results that blat is outputting. I just did a blat of human GCGR sequence, both mRNA and Protein independently(NM_000160,NP_000151) to human genome, mRNA output came out fine but the protein blat gives out no match for the first 19 amino acids. If I take just 19 a.a along with 1 more a.a(just to make the query 20 a.a long) next to it and blat it against human genome, it says no matchs.But when I blat the nucleotide sequence of the 19 a.a +1 a.a , blat do give out match. Really don't understand how is this possible. Here is my first 19+ a.a of human GCGR >test mppcqpqrpllllllllacQ
below are the results from the nucleotide blat of the above a.a: Alignment of test and chr17:79766895-79766954 Click on links in the frame to the left to navigate through the alignment. Matching bases in cDNA and genomic sequences are colored blue and capitalized. Light blue bases mark the boundaries of gaps in either sequence (often splice sites). ------------------------------------------------------------------------ -------- cDNA test ATGCCCCCCT GCCAGCCACA GCGACCCCTG CTGCTGTTGC TGCTGCTGCT 50 GGCCTGCCAG ------------------------------------------------------------------------ -------- Genomic chr17 : actcagctgc cctcggagga gcgtacacac ccaccaggac tgcattgccc 79766844 cagctgtgca gcccctgcca gatgtgggag gcagctagct gcccagaggc 79766894 ATGCCCCCCT GCCAGCCACA GCGACCCCTG CTGCTGTTGC TGCTGCTGCT 79766944 GGCCTGCCAG gtgaggactc acagcaccct cagcacccag gggccctcct 79766994 gtgaggactg cacactgatg gctctctgtc tgcctgcctg cctgcctgcc 79767044 tgtctgcctg ------------------------------------------------------------------------ -------- Side by Side Alignment 00000001 atgcccccctgccagccacagcgacccctgctgctgttgctgctgctgct 00000050 >>>>>>>> |||||||||||||||||||||||||||||||||||||||||||||||||| >>>>>>>> 79766895 atgcccccctgccagccacagcgacccctgctgctgttgctgctgctgct 79766944 00000051 ggcctgccag 00000060 >>>>>>>> |||||||||| >>>>>>>> 79766945 ggcctgccag 79766954 Notice: This e-mail message, together with any attachments, contains information of Merck & Co., Inc.
