CACTIN
Cactin also known as renal carcinoma antigen NY-REN-24 is a protein that in humans is encoded by the CACTIN gene.
Cactin was originally identified in Drosophila (fruit flies). The cactin gene is product is involved in the regulation of the innate immune system. It acts as negative regulator of the toll-like receptor, Interferon regulatory factor (IRF) and the canonical NF-kappa-B signaling pathways.
