Protein DEPPProtein DEPP also known as decidual protein induced by progesterone and fasting-induced gene protein is a protein that in humans is encoded by the DEPP gene.FunctionThe expression of this gene is induced by fasting as well as by progesterone. The protein encoded by this gene contains a t-synaptosome-associated protein receptor coiled-coil homology domain and a peroxisomal targeting signal. Production of the encoded protein leads to phosphorylation and activation of the transcription factor ELK1.
