背景 | Nectin-1 (designated CD111), also called PRR-1 (poliovirus receptor-related protein 1) or HVEC (herpesvirus entry mediator C), is a widely expressed 110 kDa type I transmembrane glycoprotein important in formation of adherens junctions and synapses. It is a member of the nectin family within the Ig superfamily (1, 2). The Latin word necto means “to connect”, indicating the role of nectins in Ca2+-independent cell-cell adhesion (2). Nectin-1 forms homodimers in cis, followed by interactions in trans with Nectin-1, -3 or -4 (2). The 517 amino acid (aa) human Nectin-1 isoform 1 contains a 30 aa signal sequence, a 325 aa extracellular domain (ECD), a 21 aa transmembrane segment (TM), and a 141 aa cytoplasmic region. Nectin ECDs contain three Ig-like domains: an N-terminal V-type that mediates ligand binding and two C2-type (3). Nectin-1, like other nectins, has a splice form (isoform 2 or HigR, 458 aa) with alternate TM and cytoplasmic sequences. Another, isoform 3, is a 352 aa secreted protein (4). The common region of mature human Nectin-1 (aa 31-334) shares 93%, 94%, 96% and 96% aa identity with mouse, rat, bovine and porcine Nectin-1, respectively. Nectin-1 binds viral glycoprotein D to mediate herpesvirus (but not poxvirus) entry into vaginal mucosa, sensory neurons and fibroblasts (4 - 7). In forming adherens junctions and synapses, nectins 1 and 3 initiate cell-cell interactions, recruiting alpha vbeta3 integrin extracellularly and cadherins intracellularly through afadin and other junctional proteins (2, 8 - 11). These interactions organize the cytoskeleton, strengthen attachment to basement membrane and promote further cell-cell connections. Nectin-1 also recognizes CD96 on NK cells (12). Deficiency of Nectin-1 can result in cleft lip/palate ectodermal dysplasia (13). Nectin-1 downregulation in epithelial cancers, mediated in part by ectodomain shedding, may contribute to invasiveness (14). |
