/ H3 / Variant: H3.5

Description

A hominid specific variant expressed in seminiferous tubules of human testis.

Features

Below, you can explore the features of H3.5 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).

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.
Keys: red - 80% identical, blue - 50% identical columns. X-ambigous positions in consensus sequence.
