BMC Evolutionary Biology (2015) 15:Page 2 of(Continued from prior web page)Conclusions: Via identification of MACITs in multiple metazoan phyla we created a model for the evolution of MACITs. The experimental data demonstrate conservation of MACIT molecular and cellular properties and tissue localisations in the invertebrate, C. elegans. Keywords: Collagen, MACIT, Molecular phylogeny, Genome paralogy, Neuromuscular junctionBackground The extracellular matrix (ECM) of metazoans is an intricate, proteinaceous meshwork that underlies all epithelia and endothelia, and surrounds all connective tissue cells. It promotes cell adhesion, migration, differentiation and proliferation, and offers a supporting structure to which cells adhere. The total genome sequences of many metazoans and specially domain arrangement research have revealed the conservation and diversity of ECM proteins in metazoans [1, 2]. Collagens are on the list of big classes of ECM macromolecules with numerous functions inside the constitution and upkeep of the ECM of most animals [3].TGF beta 2/TGFB2 Protein site Among the 28 collagen kinds identified in mammals, collagens XIII, XXIII and XXV type a subgroup of structurally related collagens which have, so far, been studied only in mammals.Complement C3/C3a Protein medchemexpress These collagens, named right here as MACITs (Membrane-Associated Collagens with Interrupted Triple-helices), are kind II transmembrane proteins, composed of a brief Nterminal cytosolic domain, a transmembrane domain and three collagenous domains (COL1-COL3), flanked and interrupted by non-collagenous sequences (NC1-NC4) (Fig. 1a) [4]. The ectodomains from the 3 collagens can be shed by furin convertases [5, 7, 8]. While the physiological functions and molecular mechanisms of MACIT collagens aren’t totally recognized, studies with genetically-engineered mouse models have recommended needs for collagen XIII within the maturation of neuromuscular junctions (NMJ) [9, 10] and for collagen XXV inside the development in the NMJ and the survival of motor neurons [11]. Additionally, collagen XXIII is up-regulated in human prostate and head and neck cancer progression [124] and collagen XXV is involved in amyloid fibril aggregation and also the formation of protease-resistantFig. 1 Domain architecture of MACIT collagens and conservation from the C-terminus.PMID:24605203 a Schematic diagrams of your domain organization of mammalian collagens XIII, XXIII and XXV, drawn to scale for the polypeptide lengths. b Various sequence alignment (MSA) of the C-termini of human and mouse MACITs. Black shading indicates residues conserved in more than 50 on the sequences, grey shading indicates semi-conserved residues, white indicates non-conserved residues. Numbers refer for the starting amino acid position. Conserved cysteine residues are indicated with asterisks. c Schematic diagrams from the domain organization of MACIT collagens from invertebrates. In (a) and (c), collagenous (COL) domains are shown in yellow, non-collagenous (NC) regions in dark blue, the NC1 domain composed of coiled-coil sequences (Coil/NC1) in pale blue, the transmembrane domain (TM) in magenta, along with the cytosolic domain (Cyto) in brown.
