Proteins/UNIPROT:O14493
Can associate with other claudins to regulate tight junction structural and functional strand dynamics. May coassemble with CLDN8 into tight junction strands containing anion-selective channels that convey paracellular chloride permeability in renal collecting ducts (By similarity). May integrate into CLDN3 strands to modulate localized tight junction barrier properties. May disrupt strand assembly of channel-forming CLDN2 and CLDN15 and inhibit cation conductance. Cannot form tight junction strands on its own..
