[annotation] osmosensor - SF 1873095

[Midori Harris]

Hi,

In SF 1873095, Donghui has requested a definition for osmosensor activity 
(GO:0005034). Can those who have used this term in annotations -- MGI, 
RGD, SGD and TAIR -- suggest anything? I'm even wondering whether it's a 
legitimate molecular function term, since a quick look at PubMed search 
results indicates that histidine kinases and adenylyl cyclases (possibly 
among other things) can be referred to as "osmosensors".

This is the SF item:
https://sourceforge.net/tracker/index.php?func=detail&aid=1873095&group_id=36855&atid=440764

These are the gene products currently annotated to GO:0005034:
MGI	MGI:1926945	Trpv4	(2 lines in file)
RGD	RGD:69337	Trpv4	(2)
SGD	S000002828	HKR1
SGD	S000003246	MSB2
SGD	S000000920	SHO1
SGD	S000001409	SLN1	(2)
TAIR	gene:3713570	ATHK1

Thanks,
Midori
