extracellular domain (ECD) found in mouse Ly-6A like lymphocyte antigens and similar proteins; ...
 25-103 4.28e-33

extracellular domain (ECD) found in mouse Ly-6A like lymphocyte antigens and similar proteins; The family includes mouse Ly-6 lymphocyte antigens, such as Ly-6A/Ly-6E, Ly-6B, Ly-6C1/6C2, Ly-6F, and Ly-6I/Ly-6M. Ly-6A/Ly-6E (also called stem cell antigen 1/SCA-1, or T-cell-activating protein/TAP) and Ly-6C are involved in T-cell activation. Members in this family contain an extracellular domain (ECD) which belongs 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).

second extracellular domain (ECD) found in Ly6/PLAUR domain-containing protein 3 (LYPD3) and similar proteins; LYPD3 (also called GPI-anchored metastasis-associated protein C4.4A homolog, or matrigel-induced gene C4 protein (MIG-C4)) supports cell migration. It may be involved in urothelial cell-matrix interactions as well as in tumor progression. LYPD3 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 second ECD.

 27-103 7.23e-03

extracellular domain (ECD) found in glycosylphosphatidylinositol-anchored high density lipoprotein-binding protein 1 (GPI-HBP1) and similar proteins; GPI-HBP1 (also called GPI-anchored HDL-binding protein 1, or high density lipoprotein-binding protein 1) is an endothelial cell transporter for lipoprotein lipase. It mediates the transport of lipoprotein lipase LPL from the basolateral to the apical surface of endothelial cells in capillaries and anchors LPL on the surface of endothelial cells in the lumen of blood capillaries. GPI-HBP1 protects LPL against loss of activity, and against ANGPTL4-mediated unfolding. Thereby, it plays an important role in lipolytic processing of chylomicrons by LPL, triglyceride metabolism and lipid homeostasis. GPI-HBP1 binds chylomicrons and phospholipid particles that contain APOA5. It also binds high-density lipoprotein (HDL) and plays a role in the uptake of lipids from HDL. GPI-HBP1 contains an extracellular domain (ECD), which belongs 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).

 27-102 8.04e-03

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.
