Acid Phosphatase 5, Tartrate Resistant (ACP5) ELISA Kit for Canine

ACP5: Involved in osteopontin/bone sialoprotein dephosphorylation. Its expression seems to increase in certain pathological states such as Gaucher and Hodgkin diseases, the hairy cell, the B-cell, and the T-cell leukemias. Defects in ACP5 are the cause of spondyloenchondrodysplasia with immune dysregulation (SPENCDI). A disease characterized by vertebral and metaphyseal dysplasia, spasticity with cerebral calcifications, and strong predisposition to autoimmune diseases. The skeletal dysplasia is characterized by radiolucent and irregular spondylar and metaphyseal lesions that represent islands of chondroid tissue within bone. ACP5 inactivating mutations result in a functional excess of phosphorylated osteopontin causing deregulation of osteopontin signaling and consequential autoimmune disease. Belongs to the metallophosphoesterase superfamily. Purple acid phosphatase family.
