CC -!- FUNCTION: [Gag-Pro-Pol polyprotein]: The matrix domain targets Gag,
CC Gag-Pro and Gag-Pro-Pol polyproteins to the plasma membrane via a
CC multipartite membrane binding signal, that includes its myristoylated
CC N-terminus. {ECO:0000250|UniProtKB:P03345}.
CC -!- FUNCTION: [Matrix protein p19]: Matrix protein.
CC {ECO:0000250|UniProtKB:P03345}.
CC -!- FUNCTION: [Capsid protein p24]: Forms the spherical core of the virus
CC that encapsulates the genomic RNA-nucleocapsid complex.
CC {ECO:0000250|UniProtKB:P03362}.
CC -!- FUNCTION: [Nucleocapsid protein p15-pro]: Binds strongly to viral
CC nucleic acids and promote their aggregation. Also destabilizes the
CC nucleic acids duplexes via highly structured zinc-binding motifs.
CC {ECO:0000250|UniProtKB:P03345}.
CC -!- FUNCTION: [Protease]: The aspartyl protease mediates proteolytic
CC cleavages of Gag and Gag-Pol polyproteins during or shortly after the
CC release of the virion from the plasma membrane. Cleavages take place as
CC an ordered, step-wise cascade to yield mature proteins. This process is
CC called maturation. Displays maximal activity during the budding process
CC just prior to particle release from the cell (Potential). Cleaves the
CC translation initiation factor eIF4G leading to the inhibition of host
CC cap-dependent translation (By similarity).
CC {ECO:0000250|UniProtKB:P03362, ECO:0000255|PROSITE-ProRule:PRU00275}.
CC -!- FUNCTION: [Reverse transcriptase/ribonuclease H, p49 subunit]: RT is a
CC multifunctional enzyme that converts the viral RNA genome into dsDNA in
CC the cytoplasm, shortly after virus entry into the cell. This enzyme
CC displays a DNA polymerase activity that can copy either DNA or RNA
CC templates, and a ribonuclease H (RNase H) activity that cleaves the RNA
CC strand of RNA-DNA heteroduplexes in a partially processive 3' to 5'-
CC endonucleasic mode. Conversion of viral genomic RNA into dsDNA requires
CC many steps. A tRNA-Pro binds to the primer-binding site (PBS) situated
CC at the 5'-end of the viral RNA. RT uses the 3' end of the tRNA primer
CC to perform a short round of RNA-dependent minus-strand DNA synthesis.
CC The reading proceeds through the U5 region and ends after the repeated
CC (R) region which is present at both ends of viral RNA. The portion of
CC the RNA-DNA heteroduplex is digested by the RNase H, resulting in a
CC ssDNA product attached to the tRNA primer. This ssDNA/tRNA hybridizes
CC with the identical R region situated at the 3' end of viral RNA. This
CC template exchange, known as minus-strand DNA strong stop transfer, can
CC be either intra- or intermolecular. RT uses the 3' end of this newly
CC synthesized short ssDNA to perform the RNA-dependent minus-strand DNA
CC synthesis of the whole template. RNase H digests the RNA template
CC except for a polypurine tract (PPT) situated at the 5' end of the
CC genome. It is not clear if both polymerase and RNase H activities are
CC simultaneous. RNase H probably can proceed both in a polymerase-
CC dependent (RNA cut into small fragments by the same RT performing DNA
CC synthesis) and a polymerase-independent mode (cleavage of remaining RNA
CC fragments by free RTs). Secondly, RT performs DNA-directed plus-strand
CC DNA synthesis using the PPT that has not been removed by RNase H as
CC primer. PPT and tRNA primers are then removed by RNase H. The 3' and 5'
CC ssDNA PBS regions hybridize to form a circular dsDNA intermediate.
CC Strand displacement synthesis by RT to the PBS and PPT ends produces a
CC blunt ended, linear dsDNA copy of the viral genome that includes long
CC terminal repeats (LTRs) at both ends (By similarity). {ECO:0000250}.

CC -!- SUBUNIT: [Gag-Pro-Pol polyprotein]: Homodimer; the homodimers are part

CC interactions are essential for budding and release of viral particles.
CC {ECO:0000250|UniProtKB:P03345}.

CC IsoId=P14076-1; Sequence=External;
CC -!- DOMAIN: Gag polyprotein: Late-budding domains (L domains) are short
CC sequence motifs essential for viral particle release. They can occur
CC individually or in close proximity within structural proteins. They
CC interacts with sorting cellular proteins of the multivesicular body
CC (MVB) pathway. Most of these proteins are class E vacuolar protein
CC sorting factors belonging to ESCRT-I, ESCRT-II or ESCRT-III complexes.
CC Matrix protein p19 contains two L domains: a PTAP/PSAP motif which
CC interacts with the UEV domain of TSG101, and a PPXY motif which binds
CC to the WW domains of the ubiquitin ligase NEDD4.
CC {ECO:0000250|UniProtKB:P03345}.
CC -!- DOMAIN: [Capsid protein p24]: The capsid protein N-terminus seems to be
CC involved in Gag-Gag interactions. {ECO:0000250|UniProtKB:P03362}.
CC -!- PTM: [Matrix protein p19]: Phosphorylation of the matrix protein p19 by
CC MAPK1 seems to play a role in budding. {ECO:0000250|UniProtKB:P03345}.
CC -!- PTM: [Gag-Pro-Pol polyprotein]: Myristoylated. Myristoylation of the
CC matrix (MA) domain mediates the transport and binding of Gag
CC polyproteins to the host plasma membrane and is required for the
CC assembly of viral particles. {ECO:0000250|UniProtKB:P03345}.
CC -!- PTM: [Gag-Pro-Pol polyprotein]: Specific enzymatic cleavages by the
CC viral protease yield mature proteins. The polyprotein is cleaved during
CC and after budding, this process is termed maturation. The protease is
CC autoproteolytically processed at its N- and C-termini.
CC {ECO:0000250|UniProtKB:P03362}.
CC -!- MISCELLANEOUS: Reverse transcriptase/ribonuclease H: The reverse
CC transcriptase is an error-prone enzyme that lacks a proof-reading
CC function. High mutations rate is a direct consequence of this
CC characteristic. RT also displays frequent template switching leading to
CC high recombination rate. Recombination mostly occurs between homologous
CC regions of the two copackaged RNA genomes. If these two RNA molecules
CC derive from different viral strains, reverse transcription will give
CC rise to highly recombinated proviral DNAs. {ECO:0000255|PROSITE-
CC ProRule:PRU00405}.
CC -!- MISCELLANEOUS: HTLV-1 lineages are divided in four clades, A
CC (Cosmopolitan), B (Central African group), C (Melanesian group) and D
CC (New Central African group). {ECO:0000305}.
CC -!- MISCELLANEOUS: [Isoform Gag-Pol polyprotein]: Produced by -1 ribosomal
CC frameshifting at the gag-pol genes boundary. {ECO:0000305}.
