Hydrolytic ATP binding site of dynein motor region; This domain is found in human cytoplasmic dynein-2 proteins. Cytoplasmic dynein-2 (dynein-2) performs intraflagellar transport and is associated with human skeletal ciliopathies. Dyneins share a conserved motor domain that couples cycles of ATP hydrolysis with conformational changes to produce movement. Structural analysis reveal that the motor's ring consists of six AAA+ domains (ATPases associated with various cellular activities: AAA1-AAA6). This is the first site (out of four nucleotide binding sites in the dynein motor) where the movement depends on ATP hydrolysis. When this site is nucleotide free or bound to ADP, the microtubule binding domain (MTBD) binds to the microtubule and the linker adopts the straight post-power-stroke conformation. Upon ATP binding and hydrolysis, the MTBD detaches from the microtubule and the linker is primed into the pre-power-stroke conformation. Dynein's AAA+ domains are each divided into an alpha/beta large subdomain designated with an L and and alpha small subdomains designated with an S. This is the AAA1 large (AAA1L) subdomain with the accompanying small subdomain (AAA1S). AAA1L, AAA1S and AAA2L enclose ADP.vanadate (ADP.Vi, ATP-hydrolysis transition state analogue). The AAA1L sensor-I loop, which varies in position depending on dynein's nucleotide state, swings in to contact AAA2L forming the important AAA1 nucleotide-binding site.

Dynein heavy chain, N-terminal region 2; Dyneins are described as motor proteins of eukaryotic cells, as they can convert energy derived from the hydrolysis of ATP to force and movement along cytoskeletal polymers, such as microtubules. This region is found C-terminal to the dynein heavy chain N-terminal region 1 (pfam08385) in many members of this family. No functions seem to have been attributed specifically to this region.

The AAA+ (ATPases Associated with a wide variety of cellular Activities) superfamily represents an ancient group of ATPases belonging to the ASCE (for additional strand, catalytic E) division of the P-loop NTPase fold. The ASCE division also includes ABC, RecA-like, VirD4-like, PilT-like, and SF1/2 helicases. Members of the AAA+ ATPases function as molecular chaperons, ATPase subunits of proteases, helicases, or nucleic-acid stimulated ATPases. The AAA+ proteins contain several distinct features in addition to the conserved alpha-beta-alpha core domain structure and the Walker A and B motifs of the P-loop NTPases.

SMC proteins are found in bacteria, archaea, and eukaryotes. This family represents the SMC protein of most bacteria. The smc gene is often associated with scpB (TIGR00281) and scpA genes, where scp stands for segregation and condensation protein. SMC was shown (in Caulobacter crescentus) to be induced early in S phase but present and bound to DNA throughout the cell cycle.

Cytoplasmic dynein-2 (dynein-2) performs intraflagellar transport and is associated with human skeletal ciliopathies. Dyneins share a conserved motor domain that couples cycles of ATP hydrolysis with conformational changes to produce movement. Structural analysis reveal that the motor's ring consists of six AAA+ domains (ATPases associated with various cellular activities (AAA1-AAA6). This is the fifth AAA+ domain subdomain AAA5S. Structural analysis reveal that it is the coiled-coil buttress interface. The relative movement of AAA5S together with the stalk (AAA4S), is coupled to rearrangements in the AAA+ ring. Closure of the AAA1 site and the rigid body movement of AAA2-AAA4 force the AAA4/AAA5 interface to close and the AAA6L subdomain to rotate towards the ring centre. The AAA5S subdomain rotates as a unit together with AAA6L, and this movement pulls the buttress relative to the stalk.

Dynein heavy chain region D6 P-loop domain; This family represents the C-terminal region of dynein heavy chain. The chain also contains ATPase activity and microtubule binding ability and acts as a motor for the movement of organelles and vesicles along microtubules. Dynein is also involved in cilia and flagella movement. The dynein subunit consists of at least two heavy chains and a number of intermediate and light chains. The 380 kDa motor unit of dynein belongs to the AAA class of chaperone-like ATPases. The core of the 380 kDa motor unit contains a concatenated chain of six AAA modules, of which four correspond to the ATP binding sites with P-loop signatures described previously, and two are modules in which the P loop has been lost in evolution. This C-terminal domain carries the D6 region of the dynein motor where the P-loop has been lost in evolution but the general structure of a potential ATP binding site appears to be retained.
