Background

Histone H2AY, also known as macro H2A1 (MH2A1) and H2AFY, is a 40 kDa variant of the histone family, basic nuclear proteins responsible for the nucleosome structure of the chromosomal fiber in eukaryotes. Ubiquitously expressed, H2AY replaces conventional H2A histones in a subset of nucleosomes, where it represses transcription and participates in stable X chromosome inactivation. H2AY expression is also enriched in senescence-associated heterochromatin. Alternative splicing creates multiple transcript variants, encoding three distinct isoforms. H2AY expressed in blood has been identified as a potential biomarker associated with the activity and therapeutic response of Huntington disease, an autosomal dominant neurodegenerative disorder. Over amino acids 230-348, human H2AY shares 98% identity with mouse and rat H2AY.
