CC   -!- FUNCTION: Myosins are actin-based motor molecules with ATPase activity
CC       (By similarity). Unconventional myosins serve in intracellular
CC       movements (By similarity). Myosin 6 is a reverse-direction motor
CC       protein that moves towards the minus-end of actin filaments (By
CC       similarity). Has slow rate of actin-activated ADP release due to weak
CC       ATP binding (PubMed:15944696). Functions in a variety of intracellular
CC       processes such as vesicular membrane trafficking and cell migration
CC       (PubMed:16917816). Required for the structural integrity of the Golgi
CC       apparatus via the p53-dependent pro-survival pathway (By similarity).
CC       Appears to be involved in a very early step of clathrin-mediated
CC       endocytosis in polarized epithelial cells (By similarity). May act as a
CC       regulator of F-actin dynamics (PubMed:7929586). As part of the DISP
CC       complex, may regulate the association of septins with actin and thereby
CC       regulate the actin cytoskeleton (By similarity). May play a role in
CC       transporting DAB2 from the plasma membrane to specific cellular targets
CC       (By similarity). May play a role in the extension and network
CC       organization of neurites (By similarity). Required for structural
CC       integrity of inner ear hair cells (By similarity). Modulates RNA
CC       polymerase II-dependent transcription (By similarity).
CC       {ECO:0000250|UniProtKB:Q64331, ECO:0000250|UniProtKB:Q9UM54,
CC       ECO:0000269|PubMed:15944696, ECO:0000269|PubMed:16917816,
CC       ECO:0000269|PubMed:7929586}.
CC   -!- SUBUNIT: Homodimer; dimerization seems to implicate the unfolding of
CC       the three-helix bundle region creating an additional calmodulin binding
CC       site, and cargo binding (PubMed:25159143, PubMed:19664948). Component
CC       of the DISP/DOCK7-induced septin displacement complex, at least
CC       composed of DOCK7, LRCH3 and MYO6 (By similarity). Able to function as
CC       a monomer under specific conditions in vitro (By similarity). Forms a
CC       complex with CFTR and DAB2 in the apical membrane of epithelial cells
CC       (By similarity). Binding to calmodulin through a unique insert, not
CC       found in other myosins, located in the neck region between the motor
CC       domain and the IQ domain appears to contribute to the directionality
CC       reversal (PubMed:15037754). This interaction occurs only if the C-
CC       terminal lobe of calmodulin is occupied by calcium (PubMed:12682054,
CC       PubMed:15037754). Interaction with F-actin/ACTN1 occurs only at the
CC       apical brush border domain of the proximal tubule cells
CC       (PubMed:7929586). Interacts with DAB2 (By similarity). In vitro, the C-
CC       terminal globular tail binds a C-terminal region of DAB2 (By
CC       similarity). Interacts with CFTR (By similarity). Interacts with OPTN
CC       (By similarity). Interacts with CABP5 (By similarity).

CC       {ECO:0000269|PubMed:7929586}. Note=Also present in endocytic vesicles
CC       (PubMed:16917816). Translocates from membrane ruffles, endocytic
CC       vesicles and cytoplasm to Golgi apparatus, perinuclear membrane and
CC       nucleus through induction by p53 and p53-induced DNA damage (By
CC       similarity). Recruited into membrane ruffles from cell surface by EGF-
CC       stimulation (By similarity). Colocalizes with DAB2 in clathrin-coated
CC       pits/vesicles (By similarity). Colocalizes with OPTN at the Golgi
CC       complex and in vesicular structures close to the plasma membrane (By
CC       similarity). {ECO:0000250|UniProtKB:Q9I8D1,
CC       ECO:0000250|UniProtKB:Q9UM54, ECO:0000269|PubMed:16917816}.
CC   -!- TISSUE SPECIFICITY: Expressed in all tissues examined including kidney
CC       cortex, intestinal mucosa, liver, lung, heart, jowl muscle, brain
CC       cortex and medulla, and in the epithelial cell line, LLC-PK1 (at
CC       protein level) (PubMed:7929586). In the kidney, located to the brush
CC       border of adult kidney proximal tubule cells (PubMed:7929586).
CC       {ECO:0000269|PubMed:7929586}.
CC   -!- DEVELOPMENTAL STAGE: Locates to the apical domain only during the final
CC       stages of kidney proximal tubule development.
CC   -!- DOMAIN: Divided into three regions: a N-terminal motor (head) domain,
CC       followed by a neck domain consisting of a calmodulin-binding linker
CC       domain and a single IQ motif, and a C-terminal tail region with a
CC       three-helix bundle region, a SAH domain and a unique globular domain
CC       required for interaction with other proteins such as cargo-binding.
CC       {ECO:0000269|PubMed:19664948, ECO:0000269|PubMed:25159143}.
CC   -!- DOMAIN: The SAH (single alpha-helix) region is characterized by a high
CC       content of charged residues which are predicted to stabilize the alpha-
CC       helical structure by ionic bonds. Its contribution to the mechanism
CC       confering the myosin movement on actin filaments is debated.
CC       {ECO:0000250|UniProtKB:Q9UM54}.
CC   -!- PTM: Phosphorylation in the motor domain, induced by EGF, results in
CC       translocation of MYO6 from the cell surface to membrane ruffles and
CC       affects F-actin dynamics. Phosphorylated in vitro by p21-activated
CC       kinase (PAK). {ECO:0000269|PubMed:12682054}.
CC   -!- SIMILARITY: Belongs to the TRAFAC class myosin-kinesin ATPase
CC       superfamily. Myosin family. {ECO:0000305}.
CC   -!- CAUTION: Represents an unconventional myosin. This protein should not
CC       be confused with the conventional myosin-6 (MYH6). {ECO:0000305}.
CC   -!- CAUTION: Originally predicted to contain a coiled coil domain but
CC       generally accepted to contain a stable SAH domain instead.
CC       {ECO:0000305}.
