CC -!- FUNCTION: Retroviral envelope proteins mediate receptor recognition and
CC membrane fusion during early infection. Endogenous envelope proteins
CC may have kept, lost or modified their original function during
CC evolution. This endogenous envelope protein has lost its original
CC fusogenic properties.
CC -!- FUNCTION: SU mediates receptor recognition. {ECO:0000250}.
CC -!- FUNCTION: TM anchors the envelope heterodimer to the viral membrane
CC through one transmembrane domain. The other hydrophobic domain, called
CC fusion peptide, mediates fusion of the viral membrane with the target
CC cell membrane (By similarity). {ECO:0000250}.
CC -!- SUBUNIT: The surface (SU) and transmembrane (TM) proteins form a
CC heterodimer. SU and TM are attached by noncovalent interactions or by a
CC labile interchain disulfide bond (By similarity). {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Virion.
CC -!- SUBCELLULAR LOCATION: [Transmembrane protein]: Cell membrane
CC {ECO:0000305}; Single-pass membrane protein {ECO:0000305}.
CC -!- DOMAIN: The CKS-17 immunosuppressive domain is present in many
CC retroviral envelope proteins. As a synthetic peptide, it inhibits
CC immune function in vitro and in vivo (By similarity). {ECO:0000250}.
CC -!- PTM: Specific enzymatic cleavages in vivo yield the mature SU and TM
CC proteins. {ECO:0000250}.
CC -!- PTM: The CXXC motif is highly conserved across a broad range of
CC retroviral envelope proteins. It is thought to participate in the
CC formation of a labile disulfide bond possibly with the CX6CC motif
CC present in the transmembrane protein (By similarity). {ECO:0000250}.
CC -!- MISCELLANEOUS: Ortholog of the human HERV-F(c)1_Xq21.33 envelope
CC protein.
CC -!- SIMILARITY: Belongs to the gamma type-C retroviral envelope protein
CC family. HERV class-I F(c)1 env subfamily. {ECO:0000305}.
CC -!- CAUTION: CKS-17 sequence does not match the minimal active consensus.
CC {ECO:0000305}.
