"Since hypomorphism of Nkx2-5 causes augmentation of Hcn4 expression in the Nkx2-5 + / Shox2 + PV myocardium [XREF_BIBR], and that the Shox2 + / Hcn4 + SV myocardium is negative for Nkx2-5, it was proposed that Nkx2-5 inhibits pacemaker properties that belong to a primitive cell phenotype, and such effect is counter balanced by Shox2."
