Kinesin motor domain, KIF2-like group; Kinesin motor domain, KIF2-like group. KIF2 is a protein expressed in neurons, which has been associated with axonal transport and neuron development; alternative splice forms have been implicated in lysosomal translocation. This catalytic (head) domain has ATPase activity and belongs to the larger group of P-loop NTPases. Kinesins are microtubule-dependent molecular motors that play important roles in intracellular transport and in cell division. In this subgroup the motor domain is found in the middle (M-type) of the protein chain. M-type kinesins are (+) end-directed motors, i.e. they transport cargo towards the (+) end of the microtubule. Kinesin motor domains hydrolyze ATP at a rate of about 80 per second, and move along the microtubule at a speed of about 6400 Angstroms per second (KIF2 may be slower). To achieve that, kinesin head groups work in pairs. Upon replacing ADP with ATP, a kinesin motor domain increases its affinity for microtubule binding and locks in place. Also, the neck linker binds to the motor domain, which repositions the other head domain through the coiled-coil domain close to a second tubulin dimer, about 80 Angstroms along the microtubule. Meanwhile, ATP hydrolysis takes place, and when the second head domain binds to the microtubule, the first domain again replaces ADP with ATP, triggering a conformational change that pulls the first domain forward.

SAM domain of TNK(ACK)-like non-receptor tyrosine-protein kinases; SAM (sterile alpha motif) domain of TNK-like subfamily is a putative protein-protein interaction domain. This subfamily includes TNK1 and TNK2 (also known as ACK1) non-receptor tyrosine-protein kinases. They contain a SAM domain at the N-terminus followed by a catalytic domain and a few other domains. Members of this group are involved in the regulation of cell adhesion and growth, receptor degradation, and axonal guidance. Deletion of the SAM domain resulted in reduction of Ack1 ability to undergo autophosphorylation and dramatically reduces ubiquitination of Ack1 catalyzed by HECT E3 ubiquitin ligase (Nedd4-1) during EGF-induced Ack1 degradation. It has been suggested that the lysine-rich region in SAM domain might be a major ubiquitination site. Members of this group are also associated with some cancers. Amplification of the Ack1 gene correlates with prostate and lung cancer progression, and Ack1 overexpression increases invasiveness. Oncogenecity of Tnk1 gene apparently depends on cell context; it may play a role in tumor suppression since Tnk1 knockout mice can develop spontaneous tumors.

of the residues that compose this conserved feature have been mapped to the query sequence.
Click on the triangle to view details about the feature, including a multiple sequence alignment
of your query sequence and the protein sequences used to curate the domain model,
where hash marks (#) above the aligned sequences show the location of the conserved feature residues.
The thumbnail image, if present, provides an approximate view of the feature's location in 3 dimensions.

This image shows a graphical summary of conserved domains identified on the query sequence.
The Show Concise/Full Display button at the top of the page can be used to select the desired level of detail: only top scoring hits
(labeled illustration) or all hits
(labeled illustration).
Domains are color coded according to superfamilies
to which they have been assigned. Hits with scores that pass a domain-specific threshold
(specific hits) are drawn in bright colors.
Others (non-specific hits) and
superfamily placeholders are drawn in pastel colors.
if a domain or superfamily has been annotated with functional sites (conserved features),
they are mapped to the query sequence and indicated through sets of triangles
with the same color and shade of the domain or superfamily that provides the annotation. Mouse over the colored bars or triangles to see descriptions of the domains and features.
click on the bars or triangles to view your query sequence embedded in a multiple sequence alignment of the proteins used to develop the corresponding domain model.
The table lists conserved domains identified on the query sequence. Click on the plus sign (+) on the left to display full descriptions, alignments, and scores.
Click on the domain model's accession number to view the multiple sequence alignment of the proteins used to develop the corresponding domain model.
To view your query sequence embedded in that multiple sequence alignment, click on the colored bars in the Graphical Summary portion of the search results page,
or click on the triangles, if present, that represent functional sites (conserved features)
mapped to the query sequence.
Concise Display shows only the best scoring domain model, in each hit category listed below except non-specific hits, for each region on the query sequence.
(labeled illustration) Standard Display shows only the best scoring domain model from each source, in each hit category listed below for each region on the query sequence.
(labeled illustration) Full Display shows all domain models, in each hit category below, that meet or exceed the RPS-BLAST threshold for statistical significance.
(labeled illustration) Four types of hits can be shown, as available,
for each region on the query sequence:
specific hits meet or exceed a domain-specific e-value threshold
(illustrated example)
and represent a very high confidence that the query sequence belongs to the same protein family as the sequences use to create the domain model
non-specific hits
meet or exceed the RPS-BLAST threshold for statistical significance (default E-value cutoff of 0.01, or an E-value selected by user via the
advanced search options)
the domain superfamily to which the specific and non-specific hits belong
multi-domain models that were computationally detected and are likely to contain multiple single domains

(CDART).
