Complex interactomes and post-translational modifications of the regulatory proteins HABP4 and SERBP1 suggest pleiotropic cellular functions

Figure 4 Global protein interaction network of hyaluronic acid binding protein 4 and serpin mRNA binding protein 1. The published interactors of hyaluronic acid binding protein 4 (HABP4) (top) and serpin mRNA binding protein 1 (SERBP1) (below) were linked to the specific domains of interaction. Proteins that interact with both N- and C-terminal domains, or the site of interaction is unknown, were linked to the blue center. Common interactors between HABP4 and SERBP1 are connected to both proteins and are located between both proteins. Red dotted lines are published interactors of HABP4, and blue dotted lines are interactors of SERBP1. HABP4: Hyaluronic acid binding protein 4; SERBP1: Serpin mRNA binding protein 1.
