Uncharacterized protein C8orf4 is a protein that in humans is encoded by the C8orf4 gene.

This gene encodes a small, monomeric, predominantly unstructured protein that functions as a positive regulator of the Wnt/beta-catenin signaling pathway. This protein interacts with a repressor of beta-catenin mediated transcription at nuclear speckles. It is thought to competitively block interactions of the repressor with beta-catenin, resulting in up-regulation of beta-catenin target genes. [provided by RefSeq, Jul 2008].
