What the grant funds

The purpose of this notice of funding opportunity (NOFO) is to solicit applications for pilot projects to elucidate a role for understudied proteins in rare disease. Awards will support generation of preliminary data and/or tools around eligible understudied protein(s). A list of eligible proteins is provided and are members of druggable protein families that have a known association with a rare disease. This NOFO is intended to jumpstart research on understudied proteins that are associated with rare diseases and provide applicants with sufficient funding to perform basic biochemical and/or biological work to further the characterization of understudied proteins within the context of rare disease.
