THE ORIGIN Bioinformatics as a subject was born when we obtained methods to read DNA and protein sequences When the number of protein and DNA sequences made manual sequence comparisons and alignments impractical
MARGARET DAYHOFF Margaret Dayhoff, 1925-1983 Started the Atlas of Protein Sequence and Structure (1969) Started the Protein Identification Resource (1972) to search for related sequences (homology) to infer evolutionary relationships (phylogeny) substition matrix, 1-letter amino acid code, point-accepted-mutations (PAM)
MILESTONES IN ALGORITHMIC DEVELOPMENT Algorithmic development in sequence comparisons Needleman-Wunch algorithm (1970) Smith-Waterman algorithm for alignment (1981) FASTP algorithm by Lipman and Pearson (1985) FASTA algorithm by Pearson, Lipman (1988) BLAST program implemented (Altshul et al.) (1990) BLAT program by Jim Kent (2000s)
DATABASES Institutes and centers for bioinformatics National Center for Biotechnological Information, NCBI (1988) European Bioinformatics Institute, EBI (1992) Famous databases established Swiss-Prot database created by University of Geneva and EMBL (1986) PRINTS database of protein motifs (Attwood and Beck) 1994 GenBank by NCBI (1982), EMBL-Bank (1980)
GENBANK (NCBI) SEQUENCE GROWTH
DATABASES CONTAINING INFORMATION OF HUMAN SEQUENCE VARIATION
COMPARATIVE GENOMICS
METAGENOMICS
COMMON PATTERN TO ALL THESE DATA
DEFINITION Computational methods for the anaylses of biological processes
IMPORTANT ASPECTS OF BIOINFORMATICS Tools that drive new biological discoveries Extends experiments one single genes - allows for generalization Have changed how we make experiments Storage, indexing, retrieval, comparison and visualization of biological data
BIOINFORMATICS-BASED DISCOVERIES Comparative genomics was imperative in identifying the microrna:rna interaction rules
GENOME-WIDE MINDSET Genomics are changing the way we ask questions in biology
When graduate students approach me these days about what is an interesting area to go into if you want to make a major contribution to biomedical research, the first thing out of my mouth is bioinformatics we are woefully short in terms of having a critical mass of people who understand both biology and computational approaches Francis Collins, director of the National Human Genome Research Institute
In the future, use of biological information collected in repositories, will play an ever increasingly important role in biology. European Molecular Biology Organization, EMBO, is considering information biology as one of the cornerstones of modern/future biology!
