histone methyltransferase complex
Definition
Target type: cellularcomponent
A multimeric complex that is able to catalyze the addition of methyl groups to histone proteins. [GOC:bf]
The histone methyltransferase (HMT) complex is a multi-protein complex responsible for catalyzing the methylation of histone proteins. These complexes are crucial for regulating gene expression, DNA replication, and other cellular processes.
The cellular component of the HMT complex can be broadly described as:
**1. Core Catalytic subunit:** This subunit directly performs the methylation reaction. It contains a SET domain, which is a conserved catalytic domain found in most HMTs. The SET domain binds to the histone substrate and utilizes S-adenosyl methionine (SAM) as a methyl donor.
**2. Scaffold/Regulatory subunit:** This subunit provides a structural framework for the complex, facilitating the assembly and interaction of other subunits. It also plays a role in recruiting the complex to specific genomic regions and regulating its activity.
**3. Reader subunit:** This subunit recognizes specific histone modifications, such as methylation or acetylation. These modifications can influence the binding of the reader subunit and further modulate the activity of the HMT complex.
**4. Other Accessory subunits:** Depending on the specific HMT complex, other accessory subunits may be present. These subunits can enhance the activity of the complex, facilitate its interaction with other cellular components, or contribute to its targeting to specific genomic regions.
**Specific examples of HMT complex components:**
* **SET domain:** The SET domain is a conserved catalytic domain found in all HMTs.
* **WD40 repeat domains:** These domains are found in many scaffolding proteins and can interact with other proteins to help assemble the HMT complex.
* **Chromodomains:** These domains can bind to methylated histones, allowing the HMT complex to target specific genomic regions.
* **PHD fingers:** These domains can recognize and bind to acetylated histones.
**Overall, the cellular component of the HMT complex is a highly dynamic and diverse entity that can vary in composition depending on the specific complex and its cellular function. This intricate architecture allows for precise control over histone methylation and ensures accurate regulation of gene expression and other cellular processes.**'
