Background: Complement Component C1rLP

C1rLP, also known as CLSPa, is a plasma serine protease that is related to the C1r complement component. C1rLP is a 487 amino acid protein that contains one CUB domain and a serine protease domain. C1rLP activates pro-C1s and pro-haptoglobin but also inhibits complement-mediated cytotoxicity. Human and mouse C1rLP share 73% aa sequence identity.
