Secondary Information

Protein Function cytoskeletal motor protein; hexameric rings that unfold proteins, dismantle DNA and RNA duplexes and pry apart macromolecular complexes and aggregates
Biochemical Properties dynein belongs to the AAA+ superfamily (ATPases associated with diverse activities); has a ring of six AAA+ modules at its core but, unusually, these are linked together into one large polypeptide, along with several unique appendages that enable motor function; operate as protein complexes built around force-generating subunits called heavy chains; Each heavy chain contains a motor domain that belongs to the AAA+ superfamily attached to a divergent amino-terminal tail domain; The tail specifies distinct oligomerization properties and serves as a platform for the binding of several types of associated subunit, which in turn mediate interactions with cargo either via direct binding or through the recruitment of adaptor proteins;
Significance in milk associated with microtubules and actin and involved in the binding and movement of vesicular cargoes, have been found in isolated MFGMs and mammary lipid droplets
