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.

P-loop containing Nucleoside Triphosphate Hydrolases; Members of the P-loop NTPase domain superfamily are characterized by a conserved nucleotide phosphate-binding motif, also referred to as the Walker A motif (GxxxxGK[S/T], where x is any residue), and the Walker B motif (hhhh[D/E], where h is a hydrophobic residue). The Walker A and B motifs bind the beta-gamma phosphate moiety of the bound nucleotide (typically ATP or GTP) and the Mg2+ cation, respectively. The P-loop NTPases are involved in diverse cellular functions, and they can be divided into two major structural classes: the KG (kinase-GTPase) class which includes Ras-like GTPases and its circularly permutated YlqF-like; and the ASCE (additional strand catalytic E) class which includes ATPase Binding Cassette (ABC), DExD/H-like helicases, 4Fe-4S iron sulfur cluster binding proteins of NifH family, RecA-like F1-ATPases, and ATPases Associated with a wide variety of Activities (AAA). Also included are a diverse set of nucleotide/nucleoside kinase families.
