LHX2 (LIM Homeobox 2) belongs to a large protein family, members of which carry the LIM domain, a unique cysteine-rich zinc-binding domain. LHX2 is involved in neuronal differentiation. LHX2 lentivirus (TET-inducible, Puro) expresses human LHX2 under the control of the Tet responsive promoter, with puromycin as a selection marker.
