CC -!- FUNCTION: Myosins are actin-based motor molecules with ATPase activity.
CC Unconventional myosins serve in intracellular movements. Their highly
CC divergent tails bind to membranous compartments, which then are moved
CC relative to actin filaments. Involved in glucose transporter recycling
CC in response to insulin by regulating movement of intracellular GLUT4-
CC containing vesicles to the plasma membrane. Component of the hair
CC cell's (the sensory cells of the inner ear) adaptation-motor complex.
CC Acts as a mediator of adaptation of mechanoelectrical transduction in
CC stereocilia of vestibular hair cells. Binds phosphoinositides and links
CC the actin cytoskeleton to cellular membranes.
CC {ECO:0000269|PubMed:16971510}.
CC -!- FUNCTION: Isoform 3 is involved in regulation of transcription.
CC Associated with transcriptional active ribosomal genes. Appears to
CC cooperate with the WICH chromatin-remodeling complex to facilitate
CC transcription. Necessary for the formation of the first phosphodiester
CC bond during transcription initiation.
CC -!- SUBUNIT: Interacts (via its IQ motifs) with CALM; this precludes
CC interaction with YWHAB. Interacts with YWHAB; this precludes
CC interaction with CALM. Interacts with RPS6 (By similarity). Interacts
CC with actin filaments. Interacts (via its IQ motifs) with CABP1 and
CC CIB1; the interaction with CABP1 and CIB1 is calcium-dependent.
CC Interacts (via tail domain) with PLEKHB1 (via PH domain); the
CC interaction is not affected by the presence or absence of calcium and
CC CALM. Interacts with POLR1A and POLR2A. Component of the B-WICH
CC complex, at least composed of SMARCA5/SNF2H, BAZ1B/WSTF, SF3B1, DEK,
CC MYO1C, ERCC6, MYBBP1A and DDX21. Interacts with GLUT4. Interacts with
CC LLPH (PubMed:26961175). {ECO:0000250, ECO:0000269|PubMed:11030652,

CC protein; Cytoplasmic side. Cell projection, stereocilium membrane.
CC Cytoplasmic vesicle. Cell projection, ruffle. Note=Colocalizes with
CC CABP1 and CIB1 at cell margin, membrane ruffles and punctate regions on
CC the cell membrane. Colocalizes in adipocytes with GLUT4 at actin-based
CC membranes. Colocalizes with GLUT4 at insulin-induced ruffles at the
CC cell membrane. Localizes transiently at cell membrane to region known
CC to be enriched in PIP2. Activation of phospholipase C results in its
CC redistribution to the cytoplasm.
CC -!- SUBCELLULAR LOCATION: [Isoform 3]: Nucleus, nucleolus. Nucleus,
CC nucleoplasm {ECO:0000250}. Nucleus, nuclear pore complex {ECO:0000250}.
CC Note=In the nucleolus, is localized predominantly in dense fibrillar
CC component (DFC) and in granular component (GC). Accumulates strongly in
CC DFC and GC during activation of transcription. Colocalizes with
CC transcription sites. Colocalizes in the granular cortex at the
CC periphery of the nucleolus with RPS6. Colocalizes in nucleoplasm with
CC RPS6 and actin that are in contact with RNP particles. Colocalizes with
CC RPS6 at the nuclear pore level (By similarity). Colocalizes with RNA
CC polymerase II in the nucleus. Colocalizes with RNA polymerase I in
CC nucleoli. {ECO:0000250}.
