SYMPK

Symplekin is a protein that in humans is encoded by the SYMPK gene.

Function
This gene encodes a nuclear protein that functions in the regulation of polyadenylation and promotes gene expression. The protein forms a high-molecular weight complex with components of the polyadenylation machinery. It is thought to serve as a scaffold for recruiting regulatory factors to the polyadenylation complex. It also participates in 3'-end maturation of histone mRNAs, which do not undergo polyadenylation. The protein also localizes to the cytoplasmic plaques of tight junctions in some cell types.

Interactions
SYMPK has been shown to interact with CSTF2, HSF1 and Oct4
