 103-190 1.09e-54

second extracellular domain (ECD) found in Ly6/PLAUR domain-containing protein 4 (LYPD4) and similar proteins; LYPD4 is an acrosome protein expressed specifically in mammalian testes and sperm. It plays an essential role in mammalian fertilization. LYPD4 contains two extracellular domains (ECDs) that belong to Ly-6 antigen/uPA receptor-like (LU) superfamily and shows snake toxin-like fold (also known as three-finger toxin/3FTx fold or three-fingered protein/TFP domain fold). This model corresponds to the second ECD domain of LYPD4.

 21-93 1.49e-32

three-fingered protein (TFP) fold found in Ly6/uPAR (LU) and snake toxin superfamily; The LU (also known as Ly-6 antigen/uPA receptor)-like extracellular domain (ECD) occurs singly in GPI-linked cell-surface glycoproteins (Ly-6 family, CD59, thymocyte B cell antigen, Sgp-2) or as three-fold repeated domain in urokinase-type plasminogen activator receptor. It is a structural domain involved in protein-protein interactions, tolerating an unusual degree of variation and binding with high specificity to a broad spectrum of targets. The snake toxin domain is present in short and long neurotoxins, cytotoxins, and short toxins, and in other miscellaneous venom peptides. The toxin acts by binding to the nicotinic acetylcholine receptors in the postsynaptic membrane of skeletal muscles and preventing the binding of acetylcholine, thereby blocking the excitation of muscles. Both the LU-like ECD and the snake toxin domain belong to three-fingered protein (TFP) fold, which is characterized by containing 70 to 100 amino acids including eight to ten cysteine residues spaced at conserved distances.

 19-90 1.36e-24

first extracellular domain (ECD) found in the Ly6/PLAUR domain-containing protein 4 (LYPD4)-like family; The LYPD4-like family includes LYPD4, testis-expressed protein 101 (TEX101), and CD177 antigen. LYPD4 is an acrosome protein expressed specifically in mammalian testes and sperm. It plays an essential role in mammalian fertilization. TEX101 (also called cell surface receptor NYD-SP8, or scleroderma-associated autoantigen, or spermatogenesis-related gene protein (SGRG)) is a germ cell-specific glycosylphosphatidylinositol (GPI)-anchored protein essential for sperm fertility and spermatogenesis. It plays a role in fertilization by controlling binding of sperm to zona pellucida and migration of spermatozoa into the oviduct. It is associated with Ly6k during spermatogenesis in testis and is required for stable expression of lymphocyte antigen 6 family member K (Ly6k) on testicular germ cells. CD177, also called human neutrophil alloantigen 2a (HNA-2a), or NB1 glycoprotein (NB1 GP), or polycythemia rubra vera protein 1 (PRV-1), is a cell surface protein normally expressed on neutrophil. It modulates the function and homeostasis of tumor-infiltrating regulatory T cells. The expression of CD177 is an important biomarker of myeloproliferative diseases. HNA-2a is expressed on subpopulations of neutrophils. Gene CD177 has two alleles: NB1 and PRV-1, which encode a glycosylphoshatidylinositol (GPI)-anchored protein with three N-glycosylation sites that belongs to the uPAR/CD59/Ly6 snake toxin superfamily. NB1 glycoprotein binds to the endothelial cell adhesion molecule, platelet endothelial cell adhesion molecule-1 (PECAM-1) and participates in neutrophil transmigration. PRV-1 is a novel hematopoietic cell surface receptor which is overexpressed in polycythemia rubra vera. LYPD4 and TEX101 contain two extracellular domains (ECDs) that belong to Ly-6 antigen/uPA receptor-like (LU) superfamily and exhibits a snake toxin-like fold (also known as three-finger toxin/3FTx fold or three-fingered protein/TFP domain fold). This model corresponds to the first ECD. CD177 contains four ECD domains. This model corresponds to the first ECD domain of LYPD4 and TEX101, as well as first and third ECD domains of CD177.

first extracellular domain (ECD) found in testis-expressed protein 101 (TEX101) and similar proteins; TEX101 (also called cell surface receptor NYD-SP8, or scleroderma-associated autoantigen, or spermatogenesis-related gene protein (SGRG)) is a germ cell-specific glycosylphosphatidylinositol (GPI)-anchored protein essential for sperm fertility and spermatogenesis. It plays a role in fertilization by controlling binding of sperm to zona pellucida and migration of spermatozoa into the oviduct. It is associated with Ly6k during spermatogenesis in testis and is required for stable expression of lymphocyte antigen 6 family member K (Ly6k) on testicular germ cells. TEX101 contains two extracellular domains (ECDs) that belong to Ly-6 antigen/uPA receptor-like (LU) superfamily and exhibits a snake toxin-like fold (also known as three-finger toxin/3FTx fold or three-fingered protein/TFP domain fold). This model corresponds to the first ECD.

fourth extracellular domain (ECD) found in CD177 antigen and similar proteins; CD177, also called human neutrophil alloantigen 2a (HNA-2a), or NB1 glycoprotein (NB1 GP), or polycythemia rubra vera protein 1 (PRV-1), is a cell surface protein normally expressed on neutrophil. It modulates the function and homeostasis of tumor-infiltrating regulatory T cells. The expression of CD177 is an important biomarker of myeloproliferative diseases. HNA-2a is expressed on subpopulations of neutrophils. Gene CD177 has two alleles: NB1 and PRV-1, which encode a glycosylphoshatidylinositol (GPI)-anchored protein with three N-glycosylation sites that belongs to the uPAR/CD59/Ly6 snake toxin superfamily. NB1 glycoprotein binds to the endothelial cell adhesion molecule, platelet endothelial cell adhesion molecule-1 (PECAM-1) and participates in neutrophil transmigration. PRV-1 is a novel hematopoietic cell surface receptor which is overexpressed in polycythemia rubra vera. Members in this family contain four extracellular domains (ECDs) that belong to Ly-6 antigen/uPA receptor-like (LU) superfamily and show snake toxin-like fold (also known as three-finger toxin/3FTx fold or three-fingered protein/TFP domain fold). The model corresponds to the fourth ECD domain of CD177.
