Immunoglobulin Heavy Variable 4–34 (IGHV4-34)

Target
IGHV4-34
Molecular classification
Immunoglobulin, B cell receptor component
01

Overview

Immunoglobulin Heavy Variable 4–34 (IGHV4-34) encodes part of the variable region of the immunoglobulin heavy chain, crucial for antigen recognition. It functions in antigen binding and mediates adaptive immune responses. Its expression on malignant B cells in various lymphomas makes it a target for precision therapies like CAR-T cell therapy.
