Web19 de mai. de 2008 · Galectins 1, 2, 3 and 9 can bind distinct cell-surface glycoprotein receptors and signal different intracellular pathways to modulate T cell survival and … WebCell-surface receptors are membrane-anchored proteins that bind to ligands on the outside surface of the cell. In this type of signaling, the ligand does not need to cross the plasma membrane. So, many different kinds of molecules (including large, hydrophilic or "water-loving" ones) may act as ligands.
WebThe SLC1A5 gene encodes a sodium-dependent neutral amino acid transporter that can act as a receptor for RD114/type D retrovirus (Larriba et al., 2001 [PubMed 11781704]).[supplied by OMIM, Jan 2011] SLC1A5 solute carrier family 1 member 5 [ (human)] ... used as receptor by HERV-W Env glycoprotein; WebLec1 cells expressing MGL1 were infected in the presence or absence of cell surface SIA, indicating that MGL1 can act as a primary receptor or as a coreceptor with SIA. Lec1 cells expressing endocytosis-deficient MGL1 mediated Ca(2+)-dependent IAV binding but were less sensitive to IAV infection, indicating that direct internalization via MGL1 can result in …
