H2A: Proteins and Enzymes

H2A is 130 amino acids long, weighs approximately 14 kDa, and is part of a group of basic nuclear proteins called histones, which are responsible for nucleosome structure of the chromosomal fiber in eukaryotes. Current studies are being done on several diseases and disorders including systemic lupus erythematosus, lupus erythematosus, x inactivation, riddle syndrome, connective tissue disease, and immunodeficiency. H2A has also been shown to have interactions with BMI1, DNAJC2, RCC1, RNF2, and SRRM1 in pathways such as the telomere maintenance, nucleosome assembly, cell cycle, and systemic lupus erythematosus pathways.
