Histone acetyltransferase KAT7 is an enzyme that in humans is encoded by the KAT7 gene. [5] [6] [7] It specifically acetylates H4 histones at the lysine12 residue (H4K12) [8] and is necessary for origin licensing and DNA replication. [9] [10] KAT7 associates with origins of replication during G1 phase of the cell cycle through complexing with CDT1. [11] Geminin is thought to inhibit the acetyltransferase activity of KAT7 when KAT7 and CDT1 are complexed together. [12]
KAT7 has been shown to interact with:
Histone acetyltransferase p300 also known as p300 HAT or E1A-associated protein p300 also known as EP300 or p300 is an enzyme that, in humans, is encoded by the EP300 gene. It functions as histone acetyltransferase that regulates transcription of genes via chromatin remodeling by allowing histone proteins to wrap DNA less tightly. This enzyme plays an essential role in regulating cell growth and division, prompting cells to mature and assume specialized functions (differentiate), and preventing the growth of cancerous tumors. The p300 protein appears to be critical for normal development before and after birth.
P300/CBP-associated factor (PCAF), also known as K(lysine) acetyltransferase 2B (KAT2B), is a human gene and transcriptional coactivator associated with p53.
Histone deacetylase 1 (HDAC1) is an enzyme that in humans is encoded by the HDAC1 gene.
The nuclear receptor coactivator 1 (NCOA1), also called steroid receptor coactivator-1 (SRC-1), is a transcriptional coregulatory protein that contains several nuclear receptor–interacting domains and possesses intrinsic histone acetyltransferase activity. It is encoded by the gene NCOA1.
DNA replication licensing factor MCM2 is a protein that in humans is encoded by the MCM2 gene.
DNA replication licensing factor MCM3 is a protein that in humans is encoded by the MCM3 gene.
Cullin-4A is a protein that in humans is encoded by the CUL4A gene. CUL4A belongs to the cullin family of ubiquitin ligase proteins and is highly homologous to the CUL4B protein. CUL4A regulates numerous key processes such as DNA repair, chromatin remodeling, spermatogenesis, haematopoiesis and the mitotic cell cycle. As a result, CUL4A has been implicated in several cancers and the pathogenesis of certain viruses including HIV. A component of a CUL4A complex, Cereblon, was discovered to be a major target of the teratogenic agent thalidomide.
Transformation/transcription domain-associated protein, also known as TRRAP, is a protein that in humans is encoded by the TRRAP gene. TRRAP belongs to the phosphatidylinositol 3-kinase-related kinase protein family.
Histone acetyltransferase KAT2A is an enzyme that in humans is encoded by the KAT2A gene.
C-terminal-binding protein 1 also known as CtBP1 is a protein that in humans is encoded by the CTBP1 gene. CtBP1 is one of two CtBP proteins, the other protein being CtBP2.
Histone acetyltransferase KAT5 is an enzyme that in humans is encoded by the KAT5 gene. It is also commonly identified as TIP60.
Protein SET, also known as Protein SET 1, is a protein that in humans is encoded by the SET gene.
CDT1 is a protein that in humans is encoded by the CDT1 gene. It is a licensing factor that functions to limit DNA from replicating more than once per cell cycle.
Chromatin assembly factor 1 subunit A is a protein that in humans is encoded by the CHAF1A gene.
K(lysine) acetyltransferase 6A (KAT6A), is an enzyme that, in humans, is encoded by the KAT6A gene. This gene is located on human chromosome 8, band 8p11.21.
K(lysine) acetyltransferase 8 (KAT8) is an enzyme that in humans is encoded by the KAT8 gene.
K(lysine) acetyltransferase 6B (KAT6B) is an enzyme that in humans is encoded by the KAT6B gene.
JADE1 is a protein that in humans is encoded by the JADE1 gene.
Histone acetyltransferase 1, also known as HAT1, is an enzyme that, in humans, is encoded by the HAT1 gene.
Origin recognition complex subunit 1 is a protein that in humans is encoded by the ORC1 gene. It is closely related to CDC6, and both are the same protein in archaea.
