Sad1 / UNC-like C-terminal; The C. elegans UNC-84 protein is a nuclear envelope protein that is involved in nuclear anchoring and migration during development. The S. pombe Sad1 protein localizes at the spindle pole body. UNC-84 and and Sad1 share a common C-terminal region, that is often termed the SUN (Sad1 and UNC) domain. In mammals, the SUN domain is present in two proteins, Sun1 and Sun2. The SUN domain of Sun2 has been demonstrated to be in the periplasm.

SUN2 helix-turn-helix domain; LINC complexes are formed by coupling of KASH (Klarsicht, ANC-1, and Syne/Nesprin Homology) and SUN (Sad1 and UNC-84) proteins from the inner and outer nuclear membranes (INM and ONM, respectively). the formation of LINC complexes by KASH and SUN proteins at the nuclear envelope (NE) establishes the physical linkage between the cytoskeleton and nuclear lamina, which is instrumental for the mechanical force transmission from the cytoplasm to the nuclear interior, and is essential for cellular processes such as nuclear positioning and migration, centrosome-nucleus anchorage, and chromosome dynamics. This entry represents an HTH domain found in SUN2 that forms a three-helix bundle to lock the SUN domain in an inactive conformation acting as an inhibitory component.

coiled-coil domain 1 of SUN domain-containing protein 2 and similar proteins; SUN domain-containing protein 2 (SUN2), also called protein unc-84 homolog B, Rab5-interacting protein (Rab5IP), or Sad1/unc-84 protein-like 2, is a component of the LINC (LInker of Nucleoskeleton and Cytoskeleton) complex which is involved in the connection between the nuclear lamina and the cytoskeleton. Besides the core SUN domain, SUN2 contains two coiled-coil domains (CC1 and CC2), which act as the intrinsic dynamic regulators for controlling the activity of the SUN domain. This model corresponds to CC1 that functions as an activation segment to release CC2-mediated inhibition of the SUN domain.

chromosome segregation protein SMC, common bacterial type; SMC (structural maintenance of chromosomes) proteins bind DNA and act in organizing and segregating chromosomes for partition. 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.

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
