Coiled coil region of thrombospondin-4 (TSP-4); This family contains the N-terminal coiled coil region of TSP-4, which is abundantly expressed in tendon and muscle, as well as in neural and osteogenic tissues, and has also been detected in brain capillaries. It forms a pentameric left-handed coiled coil with a channel that is a unique carrier for lipophilic compounds. The pentamer is stabilized by inter-subunit disulfide bonds formed between cysteine residues adjacent to the C-terminal end of the coiled coil region. TSP-4 regulates the composition of the deposition of extracellular matrix (ECM) in tendon and skeletal muscle. The absence of TSP-4 alters the organization, composition and physiological functions of these tissues. TSP-4 deficiency causes incorrect modification of heparan-sulfate (HS), resulting in decreased activity of lipoprotein lipase (LpL) and loss of beta-glycan; HS is involved in a wide variety of cellular functions, LpL is an endothelial enzyme responsible for the uptake and hydrolysis of lipoproteins, and beta-glycan has inhibiting effect on TGF-beta signaling in skeletal muscle. The human gene THBS4 that encodes for TSP-4 contains a single nucleotide polymorphism (SNP), which is expressed at high frequency in Caucasians and associated with a significantly increased risk of premature myocardial infarction. TSP-4 also binds stromal interaction molecule 1 (STIM1), a transmembrane protein that functions in the endoplasmic reticulum (ER), and regulates calcium channel activity. Studies show that TSP-4 may act as an organizer of adhesive and axon outgrowth-promoting molecules in the ECM to optimize retinal ganglion cell responses. TSP-4 is also involved in the post-translational modification of collagen and may assist in collagen fibril assembly.

Coiled coil region of thrombospondin; This domain family contains coiled coil region of subgroup B of thrombospondins, comprising TSP-3, TSP-4, and TSP-5, that assemble as pentamers. This region is located adjacent to the N-terminal domain (NTD) of thrombospondin (TSP), that mediates co-translational oligomerization via formation of a left-handed super-helix which binds hydrophilic signaling molecules such as vitamin D3 and vitamin A. Pentameric TSPs are stabilized by inter-subunit disulfide bonds formed between cysteine residues adjacent to the C-terminal end. TSP-5 is also known as cartilage oligomeric matrix protein (COMP). TSPs comprise a conserved family of extracellular, oligomeric, multidomain, calcium-binding glycoproteins. In mammals, they have several complex tissue-specific roles, including activities in wound healing and angiogenesis, connective tissue organization, vessel wall biology, and synaptogenesis, all mechanistically derived from interactions with cell surfaces, cytokines, growth factors, or components of the extracellular matrix (ECM) that together regulate many aspects of cell phenotype. In invertebrates, TSPs may have ancient functions such as bridging activities in cell-cell and cell-ECM interactions. Most protostomes and inferred basal metazoa encode a single TSP with the general domain organization of subgroup B TSPs and with a pentamerizing coiled coil.

Epidermal growth factor domain, found in epidermal growth factor (EGF) presents in a large number of proteins, mostly animal; the list of proteins currently known to contain one or more copies of an EGF-like pattern is large and varied; the functional significance of EGF-like domains in what appear to be unrelated proteins is not yet clear; a common feature is that these repeats are found in the extracellular domain of membrane-bound proteins or in proteins known to be secreted (exception: prostaglandin G/H synthase); the domain includes six cysteine residues which have been shown to be involved in disulfide bonds; the main structure is a two-stranded beta-sheet followed by a loop to a C-terminal short two-stranded sheet; Subdomains between the conserved cysteines vary in length; the region between the 5th and 6th cysteine contains two conserved glycines of which at least one is present in most EGF-like domains; a subset of these bind calcium.
