Human Papillomavirus L2 Protein (None)

Target
None
Molecular classification
Viral Capsid Protein
01

Overview

The L2 protein is the minor capsid protein of human papillomaviruses (HPVs). It plays essential roles in virion assembly and infection, including genome packaging, endosomal escape, cellular trafficking, and nuclear import. While it elicits broader cross-reactive antibodies than the major capsid protein L1, its lower abundance presents challenges for vaccine development.

02

Mechanism of action

Not applicable; the protein itself is not a drug but is a target for vaccine development and antiviral strategies.
