The function of DNAJC27 (DnaJ heat shock protein family (Hsp40) member C27, Ensembl gene identifier ENSG00000115137) is as follows. GTPase which can activate the MEK/ERK pathway and induce cell transformation when overexpressed. May act as a nuclear scaffold for MAPK1, probably by association with MAPK1 nuclear export signal leading to enhanced ERK1/ERK2 signaling. .
