What pLDDT means and how to read it

Function

Cell adhesion molecule that promotes cell-cell adhesion through heterophilic trans-interactions with nectins-like or other nectins, such as trans-interaction with NECTIN2 at Sertoli-spermatid junctions (PubMed:10744716, PubMed:11827984, PubMed:12121624, PubMed:12558799, PubMed:15328010, PubMed:16128743, PubMed:21798896). Trans-interaction with PVR induces activation of CDC42 and RAC small G proteins through common signaling molecules such as SRC and RAP1 (PubMed:16128743). Induces endocytosis-mediated down-regulation of PVR from the cell surface, resulting in reduction of cell movement and proliferation (PubMed:16128743). Involved in axon guidance by promoting contacts between the…

Subunit structure

Cis- and trans-homodimer (PubMed:10744716, PubMed:11827984). Can form trans-heterodimers with NECTIN1, NECTIN2, PVR, IGSF4B/Necl-1 and with IGSF4 (PubMed:12826663, PubMed:15741237, PubMed:16128743, PubMed:21798896). Interaction between NECTIN1 and NECTIN3 on the pre- and postsynaptic sites, respectively, initiates the formation of puncta adherentia junctions between axons and dendrites…
