Target intelligence / Profile preview

Tumor antigen (EBV-positive)

Molecular classification
Viral protein, Non-coding RNA, Antigen
01

Overview

EBV-positive tumor antigens are viral proteins and RNAs expressed in human tumors infected with Epstein-Barr virus (EBV). These antigens, including EBERs, LMPs, EBNAs, and BARF1, contribute to oncogenesis by promoting cell proliferation, inhibiting apoptosis, modulating immune responses, and inducing epigenetic changes. Their presence is a key diagnostic feature and a potential target for immunotherapy.
