extracellular domain (ECD) found in lymphocyte antigen 6D (Ly-6D) and similar proteins; Ly-6D (also called E48 antigen) is a GPI-anchored molecule apparently involved in keratinocyte cell-cell adhesion. It may act as a specification marker at earliest stage specification of lymphocytes between B- and T-cell development. Ly-6D 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).

 21-93 1.07e-06

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).

 19-93 2.98e-06

extracellular domain (ECD) found in lymphocyte antigen 6E (Ly-6E) and similar proteins; Ly-6E (also called retinoic acid-induced gene E protein (RIG-E), or stem cell antigen 2 (SCA-2), or thymic shared antigen 1 (TSA-1)) is a GPI-anchored cell surface protein that regulates T-lymphocytes proliferation, differentiation, and activation. It restricts the entry of human coronaviruses, including SARS-CoV, MERS-CoV and SARS-CoV-2, by interfering with spike protein-mediated membrane fusion. It plays an essential role in placenta formation by acting as the main receptor for syncytin-A (SynA). It may also act as a modulator of nicotinic acetylcholine receptors (nAChRs) activity. Ly-6E 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).

 21-93 9.14e-06

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.

 21-93 2.07e-04

extracellular domain (ECD) found in the secreted Ly-6/uPAR-related protein 1 (SLURP-1)-like family; The SLURP-1-like family includes SLURP-1 and Ly6/PLAUR domain-containing protein 2 (LYPD2). SLURP-1 (also called ARS component B, or ARS (component B)-81/S, or anti-neoplastic urinary protein (ANUP)) has an antitumor activity. It was found to be a marker of late differentiation of the skin. It is implicated in maintaining the physiological and structural integrity of the keratinocyte layers of the skin. In vitro SLURP-1 down-regulates keratinocyte proliferation; the function may involve the proposed role as modulator of nicotinic acetylcholine receptors (nAChRs) activity. In vitro it inhibits alpha-7-dependent nAChR currents in an allosteric manner. In T cells SLURP-1 may be involved in regulation of intracellular Ca(2+) signaling. It may also have an immunomodulatory function in the cornea. The function may implicate a possible role as a scavenger receptor for PLAU thereby blocking PLAU-dependent functions of PLAUR such as in cell migration and proliferation. LYPD2 is a lymphocyte antigen-6 family protein and shows high sequence similarity with SLURP-1. Members in this family contain an extracellular domain (ECD) that 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).

extracellular domain (ECD) found in lymphocyte antigen 6K (Ly-6K) and similar proteins; Ly-6K is required for sperm migration into the oviduct and male fertility by controlling binding of sperm to zona pellucida. It may play a role in cell growth. Ly-6K 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).

 21-94 3.01e-03

first extracellular domain (ECD) found in urokinase plasminogen activator surface receptor (uPAR) and similar proteins; uPAR (also called U-PAR, or monocyte activation antigen Mo3, or CD87) acts as a receptor for urokinase plasminogen activator. It plays a role in localizing and promoting plasmin formation. It mediates the proteolysis-independent signal transduction activation effects of U-PA. It is subject to negative-feedback regulation by U-PA which cleaves it into an inactive form. uPAR contains three 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.
