The quark self-energy is calculated in both the spacelike and timelike regions of Minkowski space from an effective one-gluon-exchange and a constant interaction. The gauge dependence of the quark mass function is analysed and the model parameters are fixed by comparison of the results to the available lattice QCD data in the spacelike region.
