Astrotactin 1/2 N-terminal; This entry represents the N-terminal domain of Astrotactin (ASTN) proteins 1 and 2, which includes the transmembrane and cytosolic regions. These are vertebrate-specific proteins involved in neuronal migration during neurodevelopment. ASTN1 is a neuronal receptor required for neuroblasts migration along glial fibers, especially in the cerebellum. ASTN2 is an endosome membrane protein that binds ASTN1 and mediates its recycling by promoting ASTN1 internalization and transport during its endocytosis.

ASTN1/2 EGF-like and Fn(III) domains; Astrotactin-1 and 2 (ASTN1/2) are integral membrane proteins with a large C-terminal domain, extracellular for ASTN1 and endosome luminal for ASTN-2. They play critical roles in neurodevelopment, and ASTN-2 is also involved in the planar cell polarity pathway in hair cells. This is a domain found in the middle of the C-terminal of ASTN-1 and 2, which comprises a EGF- like domain (EGF4) and a fibronectin type III (Fn(III)) domain. These subdomains are located between the MACPF and annexin- like domains. The structure of Fn(III) from ASTN2 revealed an unexpected feature which has two additional beta strands folded across the core. The junction between EGF-4 and Fn(III) domains in ASTN2 (but not in ASTN1) is thought to be an inositol triphosphate binding site.

MAC/Perforin domain; The membrane-attack complex (MAC) of the complement system forms transmembrane channels. These channels disrupt the phospholipid bilayer of target cells, leading to cell lysis and death. A number of proteins participate in the assembly of the MAC. Freshly activated C5b binds to C6 to form a C5b-6 complex, then to C7 forming the C5b-7 complex. The C5b-7 complex binds to C8, which is composed of three chains (alpha, beta, and gamma), thus forming the C5b-8 complex. C5b-8 subsequently binds to C9 and acts as a catalyst in the polymerization of C9. Active MAC has a subunit composition of C5b-C6-C7-C8-C9{n}. Perforin is a protein found in cytolytic T-cell and killer cells. In the presence of calcium, perforin polymerizes into transmembrane tubules and is capable of lysing, non-specifically, a variety of target cells. There are a number of regions of similarity in the sequences of complement components C6, C7, C8-alpha, C8-beta, C9 and perforin. The X-ray crystal structure of a MACPF domain reveals that it shares a common fold with bacterial cholesterol dependent cytolysins (pfam01289) such as perfringolysin O. Three key pieces of evidence suggests that MACPF domains and CDCs are homologous: Functional similarity (pore formation), conservation of three glycine residues at a hinge in both families and conservation of a complex core fold.
