Sequences collected here belong to (TS) H1.7 - a testis specific variant of H1 common in mammals. Alternate names: H1T2
Features
Below, you can explore the features of TS H1.7 from Homo sapiens, if available and how it compares to the canonical histones of the same type (first row). Canonical histone is shown in the first row, the names and descriptions of each feature can be found underneath. To explore variants from other species, please browse our curated sequences, automatically extracted sequences, or by taxonomy.
Keys: red - identical residues, blue - different residues (if more than one sequence).
General histone type features
alpha1
Alpha1-helix, first helix of winged helix-turn-helix domain
beta1
Beta-strand between two helices
alpha2
Alpha2-helix, second helix of winged helix-turn-helix domain
alpha3
Alpha3-helix
beta2
Beta-strand of short beta-sheet of C-terminal region
beta3
Beta-strand of short beta-sheet of C-terminal region
AKP helix
Positively charged carboxy-terminal domain involved in specific protein-protein and protein-DNA interactions, possibly plays roles in suppressing core histone tail domain acetylation in chromatin fiber.

A set of manually selected and validated histone sequences is listed in the table. Click on an entry in the table to update the annotated sequence preview: a variant will be compared with the canonical histone from the same species (if available).
Alternatively, tick mark the sequences and use toolbar to view MSA, export or add to basket. Use search or filters to find particular entries.
Keys: red - identical residues, blue - different residues (if more than one sequence). For feature legend see summary tab.

Keys: red - 80% identical, blue - 50% identical columns. X-ambigous positions in consensus sequence. For feature legends see summary tabs of the corresponding variant pages.
Sequence(s)
Features characteristic for a given histone type/variant are marked below the consensus sequence. For feature description see summary tabs of the corresponding variants pages.
Note: variant classification might be ambigous between very similar variants. Classification scores against all variant models are available via advanced menu.

All Profile Scores
Score shows how well a sequence was classified by a variant HMM. Each sequence has been classified as a variant (Green), but it may share similar functions to another variant (Blue). Please see the 'Help' page to learn about the classification algorithm. Score thresholds used to classify the variants are listed in parentheses.
