Rabbit Anti-CTSD (Cathepsin D, CPSD, CLN10, Lysosomal Aspartyl Protease, Ceroid-Lipofuscinosis, Neuronal 10)
Cathepsin D, is a lysosomal aspartyl protease composed of a dimer of disulfide-linked heavy and light chains, both produced from a single protein precursor. This proteinase, which is a member of the peptidase C1 family, has a specificity similar to but narrower than that of pepsin A. Transcription of this gene is initiated from several sites, including one which is a start site for an estrogen-regulated transcript. Mutations in this gene are involved in the pathogenesis of several diseases, including breast cancer and possibly Alzheimer disease. Faust et al. (1985) cloned human cathepsin D from a kidney cDNA library. The cDNA encodes a 412aa protein with 20 and 44aa in a pre- and prosegment, respectively.
