WebWe now know that 48 nuclear receptors are encoded in the human genome (Mangelsdorf et al. 1995). In many cases, ligands for these have been identified, but several “orphan receptors” remain (Burris et al. 2012). Whether all of these have bona fide ligands is unclear, because some nuclear receptors can act in the absence of a ligand (Table 1). WebHow many signal transduction pathways are there?
