Histone H3.3B: Proteins and Enzymes

Histone H3.3B is 136 amino acids long, weighs approximately 15 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, malaria, leukemia, retinoblastoma, and immunodeficiency. Histone H3.3B has also been shown to have interactions with PELP1, HIST1H4A, HIST1H4B, HIST1H4C, and HIST1H4D in pathways such as the histone modification, development notch signaling, signal transduction for Activin A, amyloids, hemostasis, meiosis, meiotic recombination, and systemic lupus erythematosus pathways.
