Fxa protease
WebA detailed understanding of blood coagulation pathways, functioning of the serine proteases thrombin, FXa, FVIIa and FIXa and elucidation of their crystal structures resulted in many potent compounds, among which some have entered the clinical phase or have been approved for use in clinical practice. WebThe protein it encodes was called RFX-associated protein (RFXAP) because it is a subunit of RFX but does not contain the characteristic RFX DBD. The human RFXAP gene is localized on chromosome 13 (Table 1 ). Several mutations affecting the RFXAP gene have been identified ( Figure 3) (reviewed in Krawczyk and Reith, 2006; Masternak et al., 2000a).
