Figure 3From: What properties characterize the hub proteins of the protein-protein interaction network of Saccharomyces cerevisiae?Functional classification of party hubs, date hubs and non-hubs. The functional classification was performed using KOG [19]. This classification consists of four main functional groups: metabolism; information storage and processing; cellular processes and signaling; and poorly characterized. Unnamed proteins have been excluded, although this is fairly common among the non-hub proteins.Back to article page
