Type:
Claudin-2 is a member of the claudin family of tight junction proteins that regulate paracellular permeability and influence cell signaling.

• High expression of CLDN2 has been associated in several studies with enhanced tumor aggressiveness, increased invasiveness, and, in some cancers (e.g., colorectal and hepatocellular carcinoma), poorer prognostic outcomes.
