The USP22 (ubiquitin-specific protease 22) antibody is a research tool used to study the function and expression of USP22. a deubiquitinating enzyme (DUB) belonging to the ubiquitin-specific protease family. USP22 plays a critical role in regulating protein stability by removing ubiquitin chains from target proteins, thereby preventing their degradation by the proteasome. It is involved in diverse cellular processes, including transcriptional regulation, cell cycle progression, and epigenetic modulation. Notably, USP22 is a component of the human transcription elongation regulator complex (hPAF complex), linking it to histone modification and gene expression control.
Research highlights USP22’s dual role in cancer biology. It is implicated in tumor progression and metastasis, often overexpressed in malignancies like colorectal, breast, and liver cancers, where it correlates with poor prognosis. USP22 is also recognized as a member of the "cancer stem cell signature," suggesting its role in maintaining stem-like properties in tumor cells. Conversely, USP22 may act as a tumor suppressor in certain contexts, emphasizing its context-dependent functions.
USP22 antibodies are widely used in techniques such as Western blotting (WB), immunohistochemistry (IHC), and immunofluorescence (IF) to detect USP22 expression levels and localization in tissues or cell lines. These studies aim to elucidate USP22’s mechanistic contributions to diseases and its potential as a therapeutic target or biomarker. Ongoing research explores targeting USP22 with small-molecule inhibitors to disrupt its oncogenic activities, underscoring its clinical relevance.
