Background of Cystatin-A antibody

Cystatins are endogenous inhibitors of lysosomal proteases that form a superfamily that is classified into three families (families 1,2 and 3) according to the homology of the amino acid sequences. Cystatin A (also termed acid cysteine proteinase inhibitor, ACPI, stefin A, and epidermal SH- proteinase inhibitor) belongs to family 1 of the cystatin superfamily of proteins. These proteins are natural inhibitors of cysteine proteinases like cathepsin B, H, L, and S. Cystatin A, a 98 amino acid protein (11-13 kDa), is detected in normal squamous epithelium, follicular dendritic cells in lymphoid tissues, thymic epithelial cells (in Hassalls corpuscles and in medulla), liver cells, granulocytes and basal epithelial cells in the prostate. Cystatin A is thought to be a tumor suppressor, since an inverse correlation seems to exist between the level of cystatin A and tumor progression, in several malignancies. Also, Cystatin A has been implicated in aging of tissues, Alzheimer disease, viral infections and inflammatory processes. Antibodies that react specifically with cystatin A are useful tools for studying structure-function relationships and cellular or subcellular localization of the molecule.
