RN [1] RP NUCLEOTIDE SEQUENCE [MRNA]. RX PubMed=2402882; DOI=10.1007/BF00678407; RA Komase K., Haga T., Yoshikawa Y., Sato T.A., Yamanouchi K.; RT "Molecular analysis of structural protein genes of the Yamagata-1 RT strain of defective subacute sclerosing panencephalitis virus. III. RT Nucleotide sequence of the hemagglutinin gene."; RL Virus Genes 4:163-172(1990). CC -!- FUNCTION: Attaches the virus to cell receptors and thereby CC initiating infection. Binding of H protein to the receptor induces CC a conformational change that allows the F protein to trigger CC virion/cell membranes fusion. May use human CD46 and/or SLAMF1 as CC receptors for viral entry into the cell. The high degree of CC interaction between H and MCP/CD46 results in down-regulation of CC the latter from the surface of infected cells, rendering them more CC sensitive to c3b-mediated complement lysis (By similarity). CC {ECO:0000250}. CC -!- SUBUNIT: Interacts with human NECTIN4; this interaction allows CC virus infection of the respiratory epithelium. Interacts with CC human MCP/CD46 antigen and SLAMF1 (By similarity). {ECO:0000250}. CC -!- SUBCELLULAR LOCATION: Virion membrane {ECO:0000305}; Single-pass CC type II membrane protein {ECO:0000305}. Host cell membrane CC {ECO:0000250}; Single-pass type II membrane protein {ECO:0000250}. CC -!- SIMILARITY: Belongs to the paramyxoviruses hemagglutinin- CC neuraminidase family. Non-sialidase subfamily. {ECO:0000305}. CC -!- CAUTION: Morbiliviruses hemagglutinins have no neuraminidase CC activity. {ECO:0000305}.
