Leucine-rich repeat-containing protein 34 (Lrrc34)

Highly expressed in stem cells in which it may be involved in regulation of pluripotency. In embryonic stem cells (ESCs), important for normal expression of the pluripotency regulators POU5F1/OCT4 and KLF4.

Also critical for expression of the ectodermal marker gene NES and the endodermal marker gene GATA4. Promotes stem cell proliferation in vitro.
