Customer Review

Based on 3 publication(s) in Google Scholar

TRIM21 Protein, an E3 ubiquitin ligase, plays a vital role in the immune response by targeting intracellular pathogens for degradation. It is involved in the recognition and clearance of viral particles. The therapeutic potential of targeting TRIM21 Protein in infectious diseases and its role in host defense make it a subject of interest in biomedical research. TRIM21 Protein, Human (P.pastoris, His) is the recombinant human-derived TRIM21 protein, expressed by P. pastoris , with N-His labeled tag.

Description

TRIM21 Protein, an E3 ubiquitin ligase, plays a vital role in the immune response by targeting intracellular pathogens for degradation. It is involved in the recognition and clearance of viral particles. The therapeutic potential of targeting TRIM21 Protein in infectious diseases and its role in host defense make it a subject of interest in biomedical research. TRIM21 Protein, Human (P.pastoris, His) is the recombinant human-derived TRIM21 protein, expressed by P. pastoris , with N-His labeled tag.

Background

The protein being described is involved in various cellular processes and pathways. It is linked to the VCP-mediated ERAD pathway, which is responsible for eliminating misfolded proteins in the endoplasmic reticulum. It promotes the ubiquitination of IRF8, enhancing its ability to stimulate the transcription of cytokine genes in macrophages. It also plays a role in regulating cell cycle progression.
