USP22 Protein, Human (sf9)

Customer Review

Based on 1 Customer Validation

USP22 protein is a histone deubiquitinating enzyme in the SAGA complex that catalyzes the deubiquitination of histones H2A and H2B and acts as a coactivator. Activators such as MYC facilitate its recruitment to gene promoters, which is critical for transcriptional activation. USP22 Protein, Human (sf9) is the recombinant human-derived USP22 protein, expressed by sf9 insect cells , with tag free.

Biological Activity

Description

USP22 protein is a histone deubiquitinating enzyme in the SAGA complex that catalyzes the deubiquitination of histones H2A and H2B and acts as a coactivator. Activators such as MYC facilitate its recruitment to gene promoters, which is critical for transcriptional activation. USP22 Protein, Human (sf9) is the recombinant human-derived USP22 protein, expressed by sf9 insect cells , with tag free.

Background

USP22 Protein serves as a histone deubiquitinating component within the transcription regulatory histone acetylation (HAT) complex SAGA. This enzyme plays a crucial role in catalyzing the deubiquitination of histones H2A and H2B, functioning as a coactivator in the process. Its recruitment to specific gene promoters is facilitated by activators such as MYC, and it proves essential for transcriptional activation. Additionally, USP22 is required for nuclear receptor-mediated transactivation and contributes to the regulation of cell cycle progression, highlighting its multifaceted involvement in key cellular processes. The dynamic interplay of USP22 within the SAGA complex underscores its significance in the orchestration of transcriptional events and cellular homeostasis.

Verified Bioactivity

The biological activity is measured by it's ability to deubiquitinate substrate Ub-rho-110 at different concentrations.
