TRPV5 (Transient receptor potential cation channel subfamily V member 5)

FEATURES

FAMILY

DESCRIPTION

Also known as TRPV5_HUMAN, TRPV5, ECAC1. Constitutively active calcium selective cation channel thought to be involved in Ca(2+) reabsorption in kidney and intestine (PubMed:11549322, PubMed:18768590). Required for normal Ca(2+) reabsorption in the kidney distal convoluted tubules (By similarity). The channel is activated by low internal calcium level and the current exhibits an inward rectification (PubMed:11549322, PubMed:18768590). A Ca(2+)-dependent feedback regulation includes fast channel inactivation and slow current decay (By similarity). Heteromeric assembly with TRPV6 seems to modify channel properties. TRPV5-TRPV6 heteromultimeric concatemers exhibit voltage-dependent gating (By similarity). Homotetramer and probably heterotetramer with TRPV6. Interacts with TRPV6 (By similarity). Interacts with S100A10 and probably with the ANAX2-S100A10 heterotetramer. The interaction with S100A10 is required for the trafficking to the plasma membrane. Interacts with calmodulin. Interacts with BSPRY, which results in its inactivation.
