Product details:
Sumoylation is a post-transcriptional modification involved in various cellular processes such as nuclear-cytoplasmic transport, transcription regulation and progression through the cell cycle. There are 3 confirmed SUMO isoforms in humans: SUMO-1, SUMO-2 and SUMO-3. SUMO-2/-3 show a high degree of similarity to each other and are distinct from SUMO-1. Sumoylation is directed by an enzymatic cascade analogous to that involved in ubiquitination. Sumoylation of target proteins
in vivo
has been shown to cause a number of different outcomes, including altered localization and binding partners.
HDAC1 is a class I histone deacetylase that plays a critical role in transcriptional repression of gene expression and has been shown to be an integral component of multiprotein co-repressor complexes. It has been observed that an important mechanism of HDAC1 activity regulation is sumoylation, which acts by potentiating HDAC1 activity.
Abcam's HDAC1 Sumoylation Assay Kit (ab115132) allows the user to measure in vivo HDAC1 sumoylation. The kit is ready-to-use and provides all the essential components needed for measuring in vivo HDAC1 sumoylation from multiple mammalian cells/tissues extracts.

HDAC1 also known as Histone Deacetylase 1 is a member of the histone deacetylase family with a molecular weight of approximately 55 kDa. Mechanically HDAC1 removes acetyl groups from lysine residues on histone proteins an action known as histone deacetylation. This process causes chromatin structure to become more compact which leads to transcriptional repression. HDAC1 is broadly expressed in various tissues particularly in the brain heart and kidneys and is vital for cellular development and differentiation.
Biological function summary
The enzymatic activity of histone deacetylase effectively controls gene expression. HDAC1 participates as a part of the multiprotein complexes including SIN3 and NuRD which play vital roles in the regulation of transcription. By altering the acetylation state of histones HDAC1 influences chromatin remodeling thereby affecting the accessibility of transcription factors to DNA and controlling genes necessary for cell cycle progression and proliferation.
Pathways
The function of HDAC1 fits into the regulation of the cell cycle and apoptosis pathways. In the cell cycle pathway HDAC1 interacts with other histone deacetylases (HDACs) and plays a role in controlling the progression of the cell division. The interplay between HDAC1 and proteins such as p53 further showcases its regulatory activity in apoptosis ensuring cell survival or programmed cell death when necessary.
HDAC1 shows significant relevance to cancer and neurodegenerative diseases. In cancer the overexpression or abnormal regulation of HDAC1 can lead to uncontrolled cell proliferation often linked to the silencing of tumor suppressor genes. Within neurodegenerative conditions HDAC1-related disturbances in gene expression may result in impaired neuronal function and survival. The involvement of HDAC1 with proteins such as p53 and other HDACs illustrates its impact on complex disease mechanisms making it a critical target for therapeutic interventions.
