BBa_K929003 1 BBa_K929003 modified AID with CMV, hGH-polyA and eGFP 2012-09-17T11:00:00Z 2015-05-08T01:13:46Z 4 parts: CMV promoter (BBa_I712004), superAID(BBa_K929001), eGFP (BBa_K404316) and hGH polyadenylation signal sequence (BBa_K404108) Released HQ 2013 The BioBrick wtAID is an extended version of the existing AID BioBrick (BBa_K929001). It is built of 3 parts: CMV promoter (BBa_I712004), superAID, eGFP (BBa_K404316) and hGH polyadenylation signal sequence (BBa_K404108).<br> AID:<br> AID is known to be responsible for somatic hypermutation and the class-switch recombination of immunoglobulin in B cells. This enzyme of 28 kDa originally occurs in B cells but does also show activity after transfection into CHO cells. AID induces the deamination of cytidine to uridine at actively transcribed single strand DNA. The replacement of cytidine by uridine leads to a mismatch during DNA replication and integrates a single base substitution predominantly in the immunoglobulin genes. <br> The AID motif is naturally terminated with the Nuclear Export Sequence (NES) that causes the protein to translocate from the nucleus to the cytoplasm. Additionally, upstream, dysfunctional Nuclear Localization Sequence (NLS) is located. Due to the fact that AID mutates the actively transcribed single stranded DNA, it is supposed that the direction of the enzyme to the inside of the nucleus would improve the mutation rate. That is why we called it superAID<br> Functional NLS sequence:<br> This part of the BioBrick directs the expressed protein into the nucleus, where it can mutate stronger. <br> Kozak sequence<br> Kozak consensus sequence is added upstream of the AID mutant to express the protein stronger.<br> CMV promoter:<br> CMV stands for cytomegalovirus. The CMV promoter is commonly used due to its very strong activity, and effectivity in a broad range of cell types. The BioBrick is therefore improved via addition of the strong promoter.<br> hGH polyadenylation signal sequence:<br> Polyadenylation is a significant part for the translation and stability of mRNA. In eukaryotes, it is part of the process that produces mature messenger RNA (mRNA) for translation. It, therefore, forms part of the larger process of gene expression. hGH terminator gives a signal to start polyadenylation in the translation process.<br> eGFP:<br> In order to test where and if the AID modified sequence is functional we added to it a eGFP protein. It is used as a marker gene for detection of transfected cells, e.g. tumor cells.<br> false false _1194_ 0 14457 9 In stock true [[Image:UP12_biobrick3.jpg]] false Potsdam Bioware 2012 iGEM annotation2203644 1 BBa_K404316 range2203644 1 1244 1966 annotation2203648 1 BBa_K404108 range2203648 1 1975 2453 annotation2203642 1 NLS sequence range2203642 1 678 696 annotation2203647 1 hGH terminator range2203647 1 1975 2453 annotation2203640 1 BBa_K929004 range2203640 1 663 1966 annotation2203646 1 UAA range2203646 1 1964 1966 annotation2203637 1 BBa_I712004 range2203637 1 1 654 annotation2203641 1 AUG range2203641 1 671 673 annotation2203639 1 BBa_K929001 range2203639 1 663 1243 annotation2203645 1 AgeI range2203645 1 1958 1963 annotation2203638 1 Kozak sequence range2203638 1 663 677 annotation2203643 1 part of BBa_K103001 range2203643 1 697 1243 BBa_K929003_sequence 1 cgatgtacgggccagatatacgcgttgacattgattattgcctagttattaatagtaatcaattacggggtcattagttcatagcccatatatggagttccgcgttacataacttacggtaaatggcccgcctggctgaccgcccaacgacccccgcccattgacgtcaataatgacgtatgttcccatagtaacgccaatagggactttccattgacgtcaatgggtggagtatttacggtaaactgcccacttggcagtacatcaagtgtatcatatgccaagtacgccccctattgacgtcaatgacggtaaatggcccgcctggcattatgcccagtacatgaccttatgggactttcctacttggcagtacatctacgtattagtcatcgctattaccatggtgatgcggttttggcagtacatcaatgggcgtggatagcggtttgactcacggggatttccaagtctccaccccattgacgtcaatgggagtttgttttggcaccaaaatcaacgggactttccaaaatgtcgtaacaactccgccccattgacgcaaatgggcggtaggcgtgtacggtgggaggtctatataagcagagctctctggctaactagagaacccactgcttactggcttatcgaaattactagagccgccaccatgggacccaagaagaggaaggtgatggacagcctcttgatgaaccggaggaagtttctttaccaattcaaaaatgtccgctgggctaagggtcggcgtgagacctacctgtgctacgtagtgaagaggcgtgacagtgctacatccttttcactggactttggttatcttcgcaataagaacggctgccacgtggaattgctcttcctccgctacatctcggactgggacctagaccctggccgctgctaccgcgtcacctggttcacctcctggagcccctgctacgactgtgcccgacatgtggccgactttctgcgagggaaccccaacctcagtctgaggatcttcaccgcgcgcctctacttctgtgaggaccgcaaggctgagcccgaggggctgcggcggctgcaccgcgccggggtgcaaatagccatcatgaccttcaaagattatttttactgctggaatacttttgtagaaaaccatgaaagaactttcaaagcctgggaagggctgcatgaaaattcagttcgtctctccagacagcttcggcgcatccttttgcccaccggccgtaaaggagaagaacttttcactggagttgtcccaattcttgttgaattagatggtgatgttaatgggcacaaattttctgtcagtggagagggtgaaggtgatgcaacatacggaaaacttacccttaaatttatttgcactactggaaaactacctgttccatggccaacacttgtcactactttcggttatggtgttcaatgctttgcgagatacccagatcatatgaaacagcatgactttttcaagagtgccatgcccgaaggttatgtacaggaaagaactatatttttcaaagatgacgggaactacaagacacgtgctgaagtcaagtttgaaggtgatacccttgttaatagaatcgagttaaaaggtattgattttaaagaagatggaaacattcttggacacaaattggaatacaactataactcacacaatgtatacatcatggcagacaaacaaaagaatggaatcaaagttaacttcaaaattagacacaacattgaagatggaagcgttcaactagcagaccattatcaacaaaatactccaattggcgatggccctgtccttttaccagacaaccattacctgtccacacaatctgccctttcgaaagatcccaacgaaaagagagaccacatggtccttcttgagtttgtaacagctgctgggattacacatggcatggatgaactatacaaaaccggttaatactagagacgggtggcatccctgtgacccctccccagtgcctctcctggccctggaagttgccactccagtgcccaccagccttgtcctaataaaattaagttgcatcattttgtctgactaggtgtccttctataatattatggggtggaggggggtggtatggagcaaggggcaagttgggaagacaacctgtagggcctgcggggtctattgggaaccaagctggagtgcagtggcacaatcttggctcactgcaatctccgcctcctgggttcaagcgattctcctgcctcagcctcccgagttgttgggattccaggcatgcatgaccaggctcagctaatttttgtttttttggtagagacggggtttcaccatattggccaggctggtctccaactcctaatctcaggtgatctacccaccttggcctcccaaattgctgggattacaggcgtgaaccactgctcccttccctgtcctt igem2sbol 1 iGEM to SBOL conversion Conversion of the iGEM parts registry to SBOL2.1 James Alastair McLaughlin Chris J.
