Histone chaperone ASF1B is a protein that in humans is encoded by the ASF1B gene. [5] [6] [7]
This gene encodes a member of the H3/H4 family of histone chaperone proteins and is similar to the anti-silencing function-1 gene in yeast. The encoded protein is the substrate of the tousled-like kinase family of cell cycle-regulated kinases, and may play a key role in modulating the nucleosome structure of chromatin by ensuring a constant supply of histones at sites of nucleosome assembly. [7]
ASF1B has been shown to interact with TLK2, [6] [8] CHAF1B, [5] [8] TLK1 [6] [8] and CHAF1A. [5] [8]
Histone H2B is one of the 5 main histone proteins involved in the structure of chromatin in eukaryotic cells. Featuring a main globular domain and long N-terminal and C-terminal tails, H2B is involved with the structure of the nucleosomes.
Histone H3.3 is a protein that in humans is encoded by the H3F3A and H3F3B genes. It plays an essential role in maintaining genome integrity during mammalian development.
Histone H3.1 is a protein that in humans is encoded by the H3C2 gene.
Histone acetyltransferase KAT2A is an enzyme that in humans is encoded by the KAT2A gene.
Histone H2B type 2-E is a protein that in humans is encoded by the HIST2H2BE gene.
Centromere protein A, also known as CENPA, is a protein which in humans is encoded by the CENPA gene. CENPA is a histone H3 variant which is the critical factor determining the kinetochore position(s) on each chromosome in most eukaryotes including humans.
High-mobility group protein B2 also known as high-mobility group protein 2 (HMG-2) is a protein that in humans is encoded by the HMGB2 gene.
Histone H2A type 2-A is a protein that in humans is encoded by the HIST2H2AA3 gene.
Chromatin assembly factor 1 subunit A is a protein that in humans is encoded by the CHAF1A gene.
Histone H2B type 1-K is a protein that in humans is encoded by the HIST1H2BK gene.
Non-histone chromosomal protein HMG-14 is a protein that in humans is encoded by the HMGN1 gene.
Histone H2B type 3-B is a protein that in humans is encoded by the HIST3H2BB gene.
Chromatin assembly factor 1 subunit B is a protein that in humans is encoded by the CHAF1B gene.
Histone H2A type 1-B/E is a protein that in humans is encoded by the HIST1H2AE gene.
Histone chaperone ASF1A is a protein that in humans is encoded by the ASF1A gene.
Serine/threonine-protein kinase tousled-like 1 is an enzyme that in humans is encoded by the TLK1 gene.
Histone H4 is a protein that in humans is encoded by the HIST1H4F gene.
Serine/threonine-protein kinase tousled-like 2 is an enzyme that in humans is encoded by the TLK2 gene.
Chromatin assembly factor-1 (CAF-1) is a protein complex — including Chaf1a (p150), Chaf1b (p60), and p48 subunits in humans, or Cac1, Cac2, and Cac3, respectively, in yeast— that assembles histone tetramers onto replicating DNA during the S phase of the cell cycle.
H4K16ac is an epigenetic modification to the DNA packaging protein Histone H4. It is a mark that indicates the acetylation at the 16th lysine residue of the histone H4 protein.
