WISE2 Algoritmos inteligentes para busca em DNA http://www.sanger.ac.uk/Software/Wise2/

O que é o WISE2 ? Wise2 é um pacote orientado à comparação de seqüências de DNA ao nível de tradução, desprezando erros de seqüenciamento e Introns. Wise2 é um pacote orientado à comparação de biopolímeros, comumente seqüências de DNA e proteínas.

DNA Exon 1 Intron A Exon 2 Intron B Exon 3 transcrição  Tradução Processo pelo qual a informação genética ( que é estocada na seqüência de nucleotídeos numa molécula de mRNA) é traduzida em uma seqüência de aminoácidos Intron Exon-GU..............................................AG-Exon DNA Exon 1 Intron A Exon 2 Intron B Exon 3 transcrição  Transcrito 5’ Exon 1 Intron A Exon 2 Intron B Exon 3 3’ Primário: Códon n Códon n+1 --------------------- Processamento do RNA  mRNA Exon 1 Exon 2 Exon 3 -- tradução  Polipeptídeo

Concorrentes: BLAST package ( NCBI) Sequence Searching Fasta package (Bill Pearson) Sequence Searching SAM package (UC Santa Cruz) HMM HMMER package (Sean Eddy) HMM Os HMMER e Pfam podem ser classificados como parceiros !!

Quais as vantagens do WISE2? O ponto forte do Wise2 é a comparação de seqüência de DNA a nível de sua tradução protéica . Implementação dos algoritmos mais robusta: Integração tecnológica faz do WISE2 o parceiro ideal para o HMMER e Pfam; Design permite reutilização e alteração do código. Manuseio de grandes pedaços de DNA sem estouro de memória;

Desvantagens O algoritmo GENEWISE não tenta predizer um gene inteiro, mas regiões que apresentam homologia com a proteína. - porém é confiável! Velocidade (Maior preocupação com a algoritmos corretos que com velocidade) Opções -u -v ( início e final de cadeia de DNA a ser comparada) Scripts em Pearl - Blastwise e Halfwise Até o momento dispõe somente de arquivos de freqüencia de genes em Humanos e Vermes. Uso de memória Linear com perda de desempenho quando uso de matrizes ultrapassam 20 MB

Modos 4 programas principais executáveis: Genewise Cadeia proteica vs Seqüência simples de DNA Genewisedb Banco de dados de proteínas vs banco de dados de seqüências de DNA. Estwise Cadeia proteica vs Seqüência simples de cDNA/EST Estwisedb Banco de dados de proteínas vs banco de dados de seqüências de cDNA/EST.

OPÇÕES -u Posição inicial no DNA -v Posição final no DNA -trev Comparação do reverso -tfor (default) Comparação standard -both Comparação nos dois sentidos -s Posição inicial na proteína - não aplicável a HMM -t Posição final na proteína - não aplicável a HMM -gap [no] default [12] gap penalty -ext [no] default [2] extension penalty -matrix default [blosum62.bla] Matriz de Comparação. Estima a probabilidade de comparações de aminoácidos -hmmer especifica que o modelo proteico é do tipo HMM -hname Nomeia o HMM -init DEFAULT
