NHP2L1NHP2-like protein 1 is a protein that in humans is encoded by the SNU13 gene.FunctionOriginally named because of its sequence similarity to the Saccharomyces cerevisiae NHP2, this protein appears to be a highly conserved nuclear protein that is a component of the tri-snRNP. It binds to the 5' stem-loop of U4 snRNA. Two transcript variants encoding the same protein have been found for this gene.InteractionsSNU13 has been shown to interact with RAD17.
