  We study the properties of 975 active galactic nuclei (AGN) selected by
variability in the Pan-STARRS1 Medium-Deep Survey. Using complementary multi
wavelength data from the ultraviolet to the far-infrared, we use SED fitting to
determine the AGN and host properties at $z<1$, and compare to a well-matched
control sample. We confirm the trend previously observed that the variability
amplitude decreases with AGN luminosity, but on the other hand, we observe that
the slope of this relation steepens with wavelength resulting in a "redder when
brighter" trend at low luminosities. Our results show that AGN are hosted by
more massive hosts than control sample galaxies, while the restframe,
dust-corrected $NUV-r$ color distribution of AGN hosts is similar to control
galaxies. We find a positive correlation between the AGN luminosity and star
formation rate (SFR), independent of redshift. AGN hosts populate the whole
range of SFRs within and outside the Main Sequence of star forming galaxies.
Comparing the distribution of AGN hosts and control galaxies, we show that AGN
hosts are less likely to be hosted by quiescent galaxies, but more likely to be
hosted by Main Sequence or starburst galaxies.
