SERTA Domain Containing 1 Human Recombinant
SERTA Domain Containing 2 Human Recombinant
The SERTA domain is a conserved protein motif found in a family of proteins known as SERTA domain-containing proteins. These proteins are involved in various cellular processes, including cell cycle regulation and transcriptional control. The SERTA domain is named after three proteins: SEI-1, RBT1, and TRIP-Br1, which share this motif .
Key Biological Properties: SERTA domain-containing proteins are involved in the regulation of cell proliferation and transcription. They are known to interact with other proteins to modulate their activity.
Expression Patterns: The expression of SERTA domain-containing proteins varies across different tissues. For instance, SERTAD1, a well-studied member of this family, is expressed in various tissues, including the brain, liver, and heart .
Tissue Distribution: SERTAD1 is predominantly localized in the nucleus and cytoplasm of cells. It is involved in the regulation of transcription and cell cycle progression .
Primary Biological Functions: SERTA domain-containing proteins play a crucial role in regulating transcription and cell cycle progression. They act as co-regulators at E2F-responsive promoters, integrating signals from PHD- and bromodomain-containing transcription factors .
Role in Immune Responses and Pathogen Recognition: While the primary focus of SERTA domain-containing proteins is on cell cycle regulation and transcription, they may also play a role in immune responses by modulating the activity of transcription factors involved in immune signaling .
Mechanisms with Other Molecules and Cells: SERTA domain-containing proteins interact with various other proteins to exert their regulatory functions. For example, SERTAD1 interacts with cyclin-dependent kinase 4 (CDK4) and enhances its activity by rendering it resistant to the inhibitory effects of CDKN2A/p16INK4A .
Binding Partners and Downstream Signaling Cascades: SERTAD1 binds to E2F1/TFDP1 transcription factors, stimulating their transcriptional activity. This interaction is crucial for the regulation of genes involved in cell cycle progression .
Regulatory Mechanisms Controlling Expression and Activity: The expression and activity of SERTA domain-containing proteins are regulated at multiple levels, including transcriptional and post-translational modifications. For instance, the transcription of SERTAD1 is regulated by various transcription factors, while its activity can be modulated by phosphorylation .
Transcriptional Regulation: SERTAD1 is regulated by transcription factors that bind to its promoter region, influencing its expression levels .
Post-Translational Modifications: Phosphorylation is a key post-translational modification that regulates the activity of SERTA domain-containing proteins. This modification can alter their interaction with other proteins and their stability .
Biomedical Research: SERTA domain-containing proteins are studied for their role in cell cycle regulation and transcription. Understanding their function can provide insights into the mechanisms of cell proliferation and cancer development .
