描述

一般說明

Membrane cofactor protein (UniProt P15529; also known as Antigen identified by monoclonal antibody TRA-2-10, CD46 antigen, Complement membrane cofactor protein, Measles virus receptor membrane cofactor protein, TLX, Trophoblast leukocyte common antigen, Trophoblast-lymphocyte cross-reactive antigen) is encoded by the CD46 (also known as MCP, TLX, AHUS2, MIC10, TRA2.10) gene (Gene ID 4179) in human. Signal 1-34, Membrane cofactor protein (MCP) or CD46 is a widely expressed complement regulator that inhibits all three pathways of complement activation, classical (CP), alternative (AP), and lectin (LP). It binds to both C3b (AP) and C4b (CP) and acts as a cofactor for their inactivation by the C3b/C4b inactivator enzyme factor I. CD46 is initially produced with an N-terminal signal sequence (a.a. 1-34), which is post-translationally removed to yield the type 1 membrane bound CD46 consisting of a large extracellular (a.a. 35-343) portion, followed by a single transmembrane α-helical region (a.a. 344-366) and a cytoplasmic tail (a.a. 367-392) with several variant structures. The extracellular portion is composed of four extracellular Complement Control Protein (CCP) domains carrying the cofactor activity, a collar STP-rich region, and a short region of unknown function (U). CD46 also acts as a receptor for certain pathogens such as the measles virus (Edmonston strain), human herpesvirus 6, and Neisseria gonorrhoeae. CD46 is also implicated to have a role in human egg fertilization. Several mutations in the CCPs and the transmembrane region of CD46 are linked to atypical hemolytic uremic syndrome (aHUS).

特異性
