DE RecName: Full=Hemagglutinin glycoprotein {ECO:0000256|ARBA:ARBA00020483}; GN Name=H {ECO:0000313|EMBL:BAB39847.1}; OS Measles morbillivirus.

OX NCBI_TaxID=11234 {ECO:0000313|EMBL:BAB39847.1}; RN [1] {ECO:0000313|EMBL:BAB39847.1} RP NUCLEOTIDE SEQUENCE. RC STRAIN=Osaka-3 {ECO:0000313|EMBL:BAB39847.1}; RX PubMed=11270608; RA Furukawa K., Ayata M., Kimura M., Seto T., Matsunaga I., Murata R., RA Yamano T., Ogura H.; RT "Hemadsorption expressed by cloned H genes from subacute sclerosing RT panencephalitis (SSPE) viruses and their possible progenitor measles RT viruses isolated in Osaka, Japan."; RL Microbiol. Immunol. 45:59-68(2001). CC -!- FUNCTION: Attaches the virus to cell receptors and thereby initiating CC infection. Binding of H protein to the receptor induces a CC conformational change that allows the F protein to trigger virion/cell CC membranes fusion. May use human CD46 and/or SLAMF1 as receptors for CC viral entry into the cell. The high degree of interaction between H and CC MCP/CD46 results in down-regulation of the latter from the surface of CC infected cells, rendering them more sensitive to c3b-mediated CC complement lysis. {ECO:0000256|ARBA:ARBA00037156}. CC -!- SUBCELLULAR LOCATION: Membrane {ECO:0000256|ARBA:ARBA00004606}; Single- CC pass type II membrane protein {ECO:0000256|ARBA:ARBA00004606}. Virion CC membrane {ECO:0000256|ARBA:ARBA00004208}; Single-pass type II membrane CC protein {ECO:0000256|ARBA:ARBA00004208}. CC -!- SIMILARITY: Belongs to the paramyxoviruses hemagglutinin-neuraminidase CC family. Non-sialidase subfamily. {ECO:0000256|ARBA:ARBA00006578}.
