[gmx-users] protein/membrane simulation parameters

I have two questions that may seem quite simple, but I haven't found clear
answers to them. It has to do with the md simulation parameters of a
solvated protein/membrane system.
The first question is about temperature. Some papers simulate at 300 K,
others at 298 K, and others at physiological temperature (310 K). I decided
that simulating at 310 K gives the most "realistic" picture of the system,
as that is biological temp. Why do many studies use 300 K? Is it incorrect
to use 310 K for this system? The goal of my work is solely to simulate a
GPCR and perform virtual screening on it.
I also decided to simulate the system at physiological salt concentration
(.15 M [NaCl]). Will this alter the conformation of my protein
