C1S Antibody / Complement C1s subcomponent

C1S, also called Complement C1s subcomponent, is a serine protease enzyme that plays a significant role in the activation of the Complement system, which is a part of the innate immune system. C1S is a key component of the C1 complex, which is the first step in the Complement activation cascade. One of the main functions of C1S is to cleave C4 and C2 proteins, leading to the formation of the C3 convertase enzyme. This enzyme then cleaves C3 protein into two parts, C3a and C3b, which mediate various immune responses such as inflammation, opsonization, and cell lysis. Overall, the activation of the Complement system through C1S plays a critical role in enhancing the immune response and clearing pathogens from our bodies. In addition to its role in immune defense, C1S has also been implicated in other physiological processes such as inflammation, tissue repair, and development. Dysregulation of C1S activity has been linked to various diseases, including autoimmune disorders, inflammatory conditions, and infectious diseases.
