target relevance
The Nectin family has at least four members (Nectin-1-4), all of which show alternate splicing, a transmembrane (TM) region (except for Nectin-1 gamma), and three extracellular Ig-domains. Nectins are highly homologous to the human receptor for poliovirus, and as such, have been alternatively-named poliovirus receptor-related proteins. They do not, however, appear to bind poliovirus. Nectin-3 (also named PRR3, CD113, and PVRL3) is an 83 kDa, type I TM glycoprotein.
Protein names Nectin-3 (CDw113) (Nectin cell adhesion molecule 3) (Poliovirus receptor-related protein 3) (CD antigen CD113)
Gene names NECTIN3,NECTIN3 PRR3 PVRL3
Protein family Nectin family
Mass 9606Da
Function Plays a role in cell-cell adhesion through heterophilic trans-interactions with nectin-like proteins or nectins, such as trans-interaction with NECTIN2 at Sertoli-spermatid junctions. Trans-interaction with PVR induces activation of CDC42 and RAC small G proteins through common signaling molecules such as SRC and RAP1. Also involved in the formation of cell-cell junctions, including adherens junctions and synapses. Induces endocytosis-mediated down-regulation of PVR from the cell surface, resulting in reduction of cell movement and proliferation. Plays a role in the morphology of the ciliary body.
Subellular location Cell membrane ; Single-pass membrane protein. Postsynaptic cell membrane .
Tissues Predominantly expressed in testis and placenta as well as in many cell lines, including epithelial cell lines.
Structure Cis- and trans-homodimer. Can form trans-heterodimers with NECTIN1, NECTIN2, PVR, IGSF4B/Necl-1 and with IGSF4. Interaction between NECTIN1 and NECTIN3 on the pre- and postsynaptic sites, respectively, initiates the formation of puncta adherentia junctions between axons and dendrites. Interacts (via Cytoplasmic domain) with AFDN, providing a connection with the actin cytoskeleton. Binds with low affinity to TIGIT.; (Microbial infection) Interacts with C.difficile toxin TcdB, suggesting that it may contribute to TcdB toxin entry into cells (PubMed:26038560). It was however shown that NECTIN3/PVRL3 does not act as a major receptor for TcdB (PubMed:27680706).
