Wikipedia pages on protein function prediction

I just received an email from Julian Gough , one of last year’s CAFA participants. He started a Wikipedia initiative on protein function prediction, which are barely stubs at the moment. EDIT: He alerted me to the fact that protein function prediction has virtually no presence on Wikipedia. So all you protein function predictors out there, please contribute. Yes, [...]

CAFA Update

Nearly a year ago, I posted about the Critical Assessment of Function prediction with which I am involved. The original post from July 22, 2010 is in the block quote. After that, an update about the meeting which will be held in exactly 2 weeks. The trouble with genomic sequencing, is that it is too [...]

Function predictor? Submit your work to the CAFA meeting

  Last July I introduced CAFA: Critical Assessment of (Gene and Protein) Function Annotations. Recap: the number of genomic and metagenomic sequences is growing at a horrendous rate. We are inundated with sequence data, yet the fraction of useful information we can glean from these sequences is steadily decreasing. There are simply too many sequences, and they are [...]

Protein Function: how do we know that we know what we know?

The trouble with genomic sequencing, is that it is too cheap. Anyone that has a bit of extra cash laying around, you can scrape the bugs off your windshield, sequence them, and write a paper. Seriously? Yes, seriously now: as we sequence more and more genomes, our annotation tools cannot keep up with them. It’s [...]

Gene and protein annotation: it’s worse than you thought

Sequencing centers keep pumping large amounts of sequence data into the omics-sphere (will I get a New Worst omics Word Award for this?)  There is no way we can annotate even a small fraction of those experimentally and indeed most  annotations are automatic, done bioinformatically. Typically function is inferred by homology: if the protein sequence [...]

A FLORA of Protein Structure to Protein Function

Proteins are the machinery of life, and they facilitate most of life’s functions. Traffic into and out of the cell? Protein pumps, pores and channels. Respiration? Proteins. Metabolism and catabolism? Proteins. Immune system, signaling, development…  all complex networks of interacting proteins. Understanding a protein’s  structure can tell us a lot about how it performs its [...]
