SNU13
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 the same protein have been found for this gene.

Interaction
Identified in the spliceosome B complex (PubMed:28781166). Component of the U4/U6-U5 tri-snRNP complex composed of the U4, U6 and U5 snRNAs and at least PRPF3, PRPF4, PRPF6, PRPF8, PRPF31, SNRNP200, TXNL4A, WDR57, SNRNP40, DDX23, CD2BP2, PPIH, NHP2L1, EFTUD2, SART1 and USP39 (PubMed:16723661, PubMed:26912367). Interacts with RAD17 and PRPF31 (PubMed:10593953, PubMed:17412961, PubMed:21784869). The complex formed by SNU13 and PRPF31 binds U4 snRNA (PubMed:17412961). The complex formed by SNU13 and PRPF31 binds also U4atac snRNA, a characteristic component of specific, less abundant spliceosomal complexes (PubMed:21784869).
