/ H1 / Variant: scH1

Description

A special variant of H1 found in Saccharomyces and probably other yeast species that has two globular domains. Saccharomyces cerevisiae has only one gene that encodes H1 histone (HHO1).

Features

Below, you can explore the features of scH1 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).
