RT "The human T-cell leukemia virus type I (HTLV-I) X region encoded protein
RT p13(II) interacts with cellular proteins.";
RL Virology 277:127-135(2000).
CC -!- FUNCTION: Connects cell membrane constituents to the actin
CC cytoskeleton. May promote orthogonal branching of actin filaments and
CC links actin filaments to membrane glycoproteins. Anchors various
CC transmembrane proteins to the actin cytoskeleton (By similarity).
CC {ECO:0000250}.
CC -!- SUBUNIT: Homodimer. Interacts with FLNA, FLNC, INPPL1, ITGB1A, ITGB1D,
CC ITGB3, ITGB6, MYOT, MYOZ1, PSEN1 and PSEN2. Interacts with MICALL2 (By
CC similarity). Interacts with RFLNA and RFLNB (By similarity). Interacts
CC with HTLV-I viral p13 protein. Interacts with ASB2; the interaction
CC targets FLNB for proteasomal degradation (By similarity). {ECO:0000250,
CC ECO:0000250|UniProtKB:Q80X90, ECO:0000269|PubMed:11062043}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm, cell cortex {ECO:0000250}. Cytoplasm,
CC cytoskeleton {ECO:0000250}. Cytoplasm, myofibril, sarcomere, Z line
CC {ECO:0000250|UniProtKB:Q80X90}.
CC -!- PTM: ISGylation prevents ability to interact with the upstream
CC activators of the JNK cascade and inhibits IFNA-induced JNK signaling.
CC {ECO:0000250}.
CC -!- PTM: Ubiquitination by a SCF-like complex containing ASB2 leads to
CC proteasomal degradation which promotes muscle differentiation.
CC {ECO:0000250|UniProtKB:O75369}.
CC -!- SIMILARITY: Belongs to the filamin family. {ECO:0000305}.
