Schematic view of the protein domains present in the novel vasculature-specific zebrafish proteins. RHOD denotes a Rhodanese homology domain; DSP, dual specificity phosphatase; CADH, cadherin repeat; CADH_C, cadherin cytoplasmic domain; 7-TM, 7 transmembrane domains; MIP, major intrinsic protein family domain; CLECT, C-type lectin; EGF-Ca, calcium binding EGF-like homology domain; EGF, EGF-like homology domain; TM, transmembrane domain; and ETS, ETS family DNA binding domain.
