Associated Protein Comments
PKD1 activates the JAK-STAT pathway, upregulating p21 (waf1) to arrest the cell cycle. Mutations disrupting the interaction between TRPP1 and PKD1 prevent the activation of this pathway and could explain why disruption of either gene leads to abnormal growth [1].
Functional Characteristics

Voltage Dependence Comments
There are few reports of current recorded from cells heterologously expressing TRPP1 alone, or in combination with PKD1. The electrophysiological properties of TRPP1 are not well established and there is disagreement as to whether measured current represent TRPP2. There are also reports that the protien is restricted to cilia in primary cells [16] and to intracellualr membranes [11] , where electrophysiological properties cannot be measured in situ with current techniques. Thus there is uncertainty about the above properties if the putative channel. If the currents do represent TRPP1, it is weakly voltage-sensitive.

Activator Comments
Activity of TRPP1 is also affected by pH in a manner that indicates the presence of an H+ ion regulatory site on the cytoplasmic side of the protein [3]

Channel Blocker Comments
The TRPP1 current has not been uniquely identified therefore the channel blockers are putative.

Functional Assay Comments
No functional assays are available as there is no definitive demonstration that the currents described so far are via the TRPP1 channel pore, nor are there molcules that specifically activate or block TRPP1.
Physiological Consequences of Altering Gene Expression
Heterozygotes: Cyst formation in kidney and liver, intracranial vascular abnormalities following sugically-induced hypertension.
Homozygotes: Embryonic lethality due to abnormal cardiac developement, cyst formation in kidney and pancreas.
Species:  Mouse
Tissue:  Various
Technique:  TRPP1 receptor knockout
References:  19,25-26
Physiological Consequences of Altering Gene Expression Comments
It is proposed that the cyst formation in heterozygotes requires a "two-hit" mechanism, where the germ-line mutation is followed by a somatic mutation leading to local homozygousity and cyst formation [26]. Increased severity of cyst formation can be seen in mice heterozygous for mutations in both TRPP1 and PKD1 [28].
