What is GFam?

GFam is a command-line tool for automatic annotation of gene families. GFam offers a framework for complete genome initiatives and model organism resources to build domain-based gene families, derive meaningful functional labels and maintain family annotation across genome releases seamlessly. Our approach achieves a unified system for grouping proteins based on evolutionary and functional relationships.

GFam can generally be considered stable. We have used it successfully to annotate the whole genome of Arabidopsis thaliana and Arabidopsis lyrata, and we also managed to build gene families for Caenorhabditis elegans, Daphnia pulex, Danio rerio, Dictyostelium discoideum, Drosophila melanogaster, Gallus gallus, Mus musculus and Neurospora crassa.
