 26-113 4.92e-45

extracellular domain (ECD) found in lymphocyte antigen 6H (Ly-6H) and similar proteins; Ly-6H may act as a modulator of nicotinic acetylcholine receptors (nAChRs) activity. In vitro it inhibits alpha-3:beta-4-containing nAChRs maximum response. Ly-6H may play a role in the intracellular trafficking of alpha-7-containing nAChRs and may inhibit their expression at the cell surface. It seems to inhibit alpha-7/CHRNA7 signaling in hippocampal neurons. Ly-6H 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).

 24-111 6.44e-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).

 24-111 1.98e-05

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).

extracellular domain (ECD) found in prostate stem cell antigen (PSCA) and similar proteins; PSCA may be involved in the regulation of cell proliferation. It has a cell-proliferation inhibition activity in vitro. PSCA may also act as a modulator of nicotinic acetylcholine receptors (nAChRs) activity. In vitro it inhibits nicotine-induced signaling probably implicating alpha-3:beta-2- or alpha-7-containing nAChRs. PSCA 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).
