It has been considered the most ubiquitous receptor for herpesviruses. However, in the context of flavivirus infection, its role was previously unknown. In this study, we described an arrayed siRNA screen mainly targeting Ig-like proteins that showed NECTIN1-restricted bovine viral diarrhea virus (BVDV) infection. We demonstrated that the depletion of NECTIN1 could significantly enhance the infection of both biotypes and multiple genotypes of BVDV, including BVDV-1a, -1b, -1c, -1p, -1m, -1v, and -2a. Notably, the IgV of NECTIN1 has emerged as the key domain restricting BVDV infection. Moreover, NECTIN1 inhibited BVDV attachment without exerting a significant influence on BVDV translation or transcription. Furthermore, we demonstrated that both NECTIN1 and CD46 could bind to BVDV E2, while the binding affinity of NECTIN1 for BVDV E2 was greater than that for CD46. We further identified that the BVDV E2 domain DD was a key domain of BVDV interacting with NECTIN1. In addition, we showed that NECTIN1 inhibited infections by classical swine fever virus (CSFV), Japanese encephalitis virus (JEV), and Zika virus (ZIKV), which belong to the\n              <jats:italic>Flaviviridae<\/jats:italic>\n              family, but had limited effects on bluetongue virus (BTV), vesicular stomatitis virus (VSV), Akabane virus (AKAV), and Sindbis virus (SINV). Overall, our study has important implications for understanding the entry of BVDV and revealed a novel role for NECTIN1 as a restriction factor that inhibits flavivirus infection.\n            <\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>IMPORTANCE<\/jats:title>\n            <jats:p>\n              NECTIN1, also known as CD111 or PVRL1, has been recognized as the primary receptor for several alpha herpesviruses, including herpes simplex virus (HSV), pseudorabies virus (PRV), and bovine herpesvirus 1 (BHV-1). However, our study revealed a novel role for NECTIN1 in the virus life cycle by influencing BVDV infection. Contrary to its role as a receptor for alpha herpesviruses, NECTIN1 acts as a restriction factor for BVDV by inhibiting viral attachment via competition with CD46 for binding to the domain DD of BVDV E2. We further revealed that the replication of members of the\n              <jats:italic>Flaviviridae<\/jats:italic>\n              family was inhibited by NECTIN1, while the replication of other RNA viruses did not significantly differ. Our results demonstrate that NECTIN1 is a novel factor restricting\n              <jats:italic>Flaviviridae<\/jats:italic>\n              family virus replication and highlight the complexity of
