The second receptor for C5a is a new addition to the complement family since the first edition of this book. It was discovered in and, despite its relatively short history, its function has been the subject of controversy. The genetic locus for this receptor consists of two exons separated by a large intron, a structure it shares with C5aR1.

Complement component 4 (C4), in humans, is a protein involved in the intricate complement system, originating from the human leukocyte antigen (HLA) system. It serves a number of critical functions in immunity, tolerance, and autoimmunity with the other numerous components.

The classical pathway of complement activation is initiated by the interaction of immunocomplexes (macromolecular aggregates of immunoglobulin bound to its antigen) with complement component C1. Immunocomplex binding activates C1 to cleave C4 and C2, forming a heterodimer composed of C4 and C2 cleavage products, which is called the classical C3.

A macromolecule is a very large molecule, such as protein, commonly composed of the polymerization of smaller subunits called are typically composed of thousands of atoms or more.

The most common macromolecules in biochemistry are biopolymers (nucleic acids, proteins, and carbohydrates) and large non-polymeric molecules (such as lipids and macrocycles).

In serum, it is part of a calcium-dependent penta molecular complex containing one molecule ofClq and two molecules each of the pro enzymes Clr and CIs. During classical pathway activation, the macromolecular complex becomes associated with the activator through the Clq subcomponent.

Reader Mode. Molecular biology aims to explain cellular processes in terms of the individual molecular players, resulting in starring roles for certain specific proteins, RNAs and lipids. Macromolecular complexes are cellular machines that perform a wide array of vital tasks.

Understanding their structure is crucial to understanding their function, and will shed light on how the cell functions in health and disease.

Current techniques offer some insights into the structure of these machines, but new and more powerful methods are needed to elucidate them fully.

Abstract. Complement was first described as a heat-labile component in serum with bactericidal activity.

It was subsequently found to also participate in many aspects of host defense against infection, including the initiation of inflammation, opsonization of microorganisms, and regulation of the immune response.

The major focus of Dr. Ghebrehiwet’s laboratory is to dissect the role of C1q and its receptors (cC1qR and gC1qR) in inflammation, infection, autoimmunity and cancer.

The first component of complement, C1, is a multimolecular complex comprising of C1q and a Ca2+-dependent tetramer, C1r2–C1s2. Guillain–Barré syndrome, an autoimmune neuropathy characterized by acute limb weakness, is often preceded by Campylobacter jejuni infection.

Molecular mimicry exists between the bacterial lipo-oligosaccharide and human ganglioside. Such C. jejuni infection induces production of immunoglobulin G1 (IgG1) autoantibodies against GM1 and causes complement-mediated motor nerve Saeko Yanaka, Rina Yogo, Hiroki Watanabe, Yuki Taniguchi, Tadashi Satoh, Naoko Komura, Hiromune Ando.

Structure and function []. MAC is composed of a complex of four complement proteins (C5b, C6, C7, and C8) that bind to the outer surface of the plasma membrane, and many copies of a fifth protein (C9) that hook up to one another, forming a ring in the membrane.C6-C9 all contain a common MACPF domain; this region is homologous to cholesterol-dependent cytolysins from Gram-positive bacteria.
