Rabbit (Oryctolagus cuniculus) red cell and tissue acid phosphatases were studied by means of horizontal starch gel electrophoresis and isoelectric focusing followed by enzyme blotting. Red cell acid phosphatase 1 (ACP1) is monomorphic while tissue acid phosphatase 2 (ACP2) is polymorphic in a wild rabbit population, with two alleles: ACP21 (0.96) and ACP22 (0.04). A third locus homologous of human acid phosphatase 3 (ACP3) is characterized by the presence of three alleles (ACP31, ACP32 and ACP33). ACP31 is the most common allele and was detected in all populations, ACP32 was found in domestic breeds and in a wild population from Southern France, whereas ACP33 is typical of Portuguese wild rabbits. The geographical distribution of ACP32 and ACP33 is in agreement with the subspecific level of differentiation of the rabbit species in O. cuniculus cuniculus and O. c. algirus. The comparative study of the acid phosphatase activity in red cells of several mammalian species, including humans, suggests that ACP3 activity in erythrocytes exists only in rabbit.
