Testis-specific serine kinase substrate; TSKS, testis-specific serine kinase substrate, is expressed in the testis and is downregulated in cancerous testicular tissue, in comparison with adjacent normal tissue. TSKS expression is very low to undetectable in seminoma, teratocarcinoma, embryonal, and Leydig cell tumours, while high in testicular tissue adjacent to tumours which contain pre-malignant carcinoma in situ. Recently it has been shown in human testis to be localized to the equatorial segment of ejaculated human sperm. The finding of a TSKS family member in mature sperm suggests that this family of kinases might play a role in sperm function. TSKS is localized during spermiogenesis to the centrioles of post-meiotic spermatids, where it reaches its greatest concentration during the period of flagellogenesis.

Growth-arrest specific micro-tubule binding; This family is the highly conserved central region of a number of metazoan proteins referred to as growth-arrest proteins. In mouse, Gas8 is predominantly a testicular protein, whose expression is developmentally regulated during puberty and spermatogenesis. In humans, it is absent in infertile males who lack the ability to generate gametes. The localization of Gas8 in the motility apparatus of post-meiotic gametocytes and mature spermatozoa, together with the detection of Gas8 also in cilia at the apical surfaces of epithelial cells lining the pulmonary bronchi and Fallopian tubes suggests that the Gas8 protein may have a role in the functioning of motile cellular appendages. Gas8 is a microtubule-binding protein localized to regions of dynein regulation in mammalian cells.

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)

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) 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
