Background Information

CTSD(Cathepsin D) is also named as CPSD,belongs to the peptidase A1 family.It is ubiquitously expressed and is involved in proteolytic degradation, cell invasion, and apoptosis. The prepro- CTSD isoform has a molecular mass of 52 kDa, the pro-CTSD 48 kDa and the mature CTSD 32 kDa(PMID:10917609). It is a lysosomal acid protease found in neutrophils and monocytes and involved in the pathogenesis of several diseases such as breast cancer and possibly Alzheimer disease.Defects in CTSD are the cause of neuronal ceroid lipofuscinosis type 10 (CLN10).
