We report on measurements of quantized conductance in gate-defined quantumpoint contacts in bilayer graphene that allow the observation of subbandsplittings due to spin-orbit coupling. The size of this splitting can be tunedfrom 40 to 80 $\mu$eV by the displacement field. We assign this gate-tunablesubband-splitting to a gap induced by spin-orbit coupling of Kane-Mele type,enhanced by proximity effects due to the substrate. We show that thisspin-orbit coupling gives rise to a complex pattern in low perpendicularmagnetic fields, increasing the Zeeman splitting in one valley and suppressingit in the other one. In addition, we observe the existence of a spin-polarizedchannel of 6 e$^2$/h at high in-plane magnetic field and of signatures ofinteraction effects at the crossings of spin-split subbands of opposite spinsat finite magnetic field.
