Clinical significance of tartrate-sensitive and tartrate-resistant acid phosphatase indicated from the study of their biosynthetic mechanism.
The tartrate-sensitive prostatic acid phosphatase, bands 2 and 4, are found in the soluble cytosol, and absent in the polysome of the prostate, while the tartrate-resistant acid phosphatase band 5 is present in the polysome and the soluble cytosol of hairy cells. The mRNA isolated from the prostate catalyzes the incorporation of 3T leucine into a protein different from that of bands 2 and 4. On the other hand, the mRNA isolated from the hairy cells catalyzes the incorporation of 3T leucine into band 5. The different biosynthetic mechanism of these two types of acid phosphatases are discussed in light of their different clinical significance.
