Originally named because of its sequence similarity to the Saccharomyces cerevisiae NHP2 (non-histone protein 2), this protein appears to be a highly conserved nuclear protein that is a component of the [U4/U6.U5] tri-snRNP. It binds to the 5' stem-loop of U4 snRNA. Two transcript variants encoding
SNU13 homolog, small nuclear ribonucleoprotein (U4/U6.U5)
Enables box C/D sno(s)RNA binding activity. Involved in box C/D snoRNP assembly. Acts upstream of or within single fertilization. Part of box C/D methylation guide snoRNP complex. Is expressed in head. Orthologous to human SNU13 (small nuclear ribonucleoprotein 13). [provided by Alliance of Genome R
