Analysis of storage bodies in the ceroid‐lipofuscinoses (Batten disease) has demonstrated a high protein content suggestive of a proteinosis. Direct N‐terminal sequencing has shown that subunit c of mitochondrial ATP synthase is specifically stored in the disease in sheep and cattle, and in the human late infantile and juvenile diseases, as well as in 3 breeds of dogs. No differences have been found between the stored subunit c and that in normal mitochondria. No other mitochondrial components are stored. Different proteins, sphingolipid activator proteins (SAPs or saposins) A and D, are stored in the infantile disease.Linkage studies have shown that different forms of ceroid‐lipofuscinosis are coded for on different genes on different chromosomes. The genes for subunit c, its production, its insertion into mitochondria, and mitochondrial function are normal. This suggests that underlying the various forms of the disease is a family of lesions in the normal pathway of subunit c turnover, after its normal insertion into the ATP synthase complex.Antibodies to subunit c offer one way of mapping that pathway and detecting the sites of lesions. Specific antibodies have been raised against stored subunit c, using a liposomal adjuvant system which proved superior to classical adjuvants. These antibodies are also useful diagnostically, both in Western blotting and in immunocytochemistry.
