Extragalactic maser sources associated with the Active Galactic Nuclei (AGNs), named megamasers, are unique tools to derive fundamental physical quantities of the host galaxies.
Those associated with accretion disks around the supermassive black holes (SMBHs) are used to trace the disk geometry, to estimate the BH mass and to measure accurate distances to their host galaxies.
Masers associated with radio jets and/or nuclear outflow are used to provide important information about the interaction region of the
jets/outflow with the interstellar medium.
In order to perform such studies, high angular resolution measurements are fundamental and, in particular, those obtained by using the Very Long Baselines Interferometry (VLBI) technique through existing arrays.
In this proceeding, we present preliminary results about the megamaser LINER galaxy IC 485, part of a Ph.D project.
The outcome reveals a maser emission resolved in two main groups of features, spatially distinguished and separated in velocity by about 500 km/s, one centered at the systemic velocity of the nuclear region of IC 485 and the other one red-shifted.
Our study is discussed in the framework of a new possible disk and/or jet maser source in the galaxy.
