ANTI-MYOSIN VI (KA-15) DEVELOPED IN RABBIT AFFINITY ISOLATED ANTIBODY

General description

Myosin VI (MYO6) is localized to the Golgi complex and is expressed in the hair cells of the ear. It is a two-headed myosin with a short coiled-coil segment in its tail. The motor domain of MYO6 has two insertions. The gene encoding this protein is localized on chromosome 6q13.

Myosin VI is a relatively abundant widespread unconventional myosin composed of an N-terminal motor domain, a light chain binding neck region, a coiled-coiled region, and a highly conserved C-terminal domain. At the ′converter′ region, between the catalytic head and the neck region of Myosin VI, there is a characteristic linker about 50 amino acids long. Native Myosin VI is apparently a two-headed dimer of the heavy chains with each heavy chain bound to calmodulin light chain.

Immunogen

synthetic peptide corresponding to an epitope within the C-terminal of human Myosin VI, with N-terminal cysteine added, conjugated to KLH.

Application

Anti-Myosin VI (KA-15) antibody has been used:

• in immunoblotting
• in immunocytochemistry
• in immunofluorescence
• immunohistochemistry
• proximity ligation assay

Biochem/physiol Actions

Myosin VI participates in the generation of cell shape change, cell motility, membrane remodeling, and possibly in organelle and particle transport or tethering. It is also involved in membrane trafficking pathways in cultured mammalian cells where it is associated with the membrane ruffles and the trans-Golgi network. The unusual direction of Myosin VI movement may suggest that it brings materials or membranes into the cell. Its activity in tissue cultured cells is thought to be regulated by phosphorylation. A mutation in Myosin VI was described recently in human autosomal dominant non syndromic hearing loss.
