Histone H2B
The N terminus tail of histone H2B is essential for chromatin condensation. [Anne-Elisabeth de la Barre et al ,(2001) ]
It is markedly deficient in variants. However research has reported two
testis specific variants of H2B.[Kavitha
Sarma et al,(2005)]. These appear to
have very specialized functions in chromatin compaction and transcription,
repression, particularly during gametogenesis
