PHYSICAL PROPERTIES

STRUCTURE

motifs/domains	four PDZ/DHR domains
	among which PDZ domain 3 binds with Na-phosphate cotransporter IIa and and PDZ domain 4 with TRPV6

HOMOLOGY

interspecies

ortholog to murine Pdzk2

Homologene

FAMILY

superfamily of class I PDZ proteins

CATEGORY

regulatory

SUBCELLULAR LOCALIZATION	intracellular
	intracellular,cytoplasm,cytosolic

basic FUNCTION	may inhibit the catalytic activity of GCC by binding to its COOH terminal
	essential TRPV6 interacting protein as a physiological modulator of TRPV6

CELLULAR PROCESS

PHYSIOLOGICAL PROCESS

PATHWAY

metabolism

signaling

a component

INTERACTION

DNA

RNA

small molecule

protein	GCC binding
	interacts with TRPV6 through its fourth PDZ domain
	interacts with Na-phosphate cotransporter IIa and induced endocytosis of Na-phosphate cotransporter IIa, which in turn result in Na and phosphate excretion in the urine
