Protein Structure

UniProt Annotation

Function

Functions as a scaffold that mediates the ordered assembly of spliceosomal proteins and snRNAs. Required for the assembly of the U4/U6-U5 tri-snRNP complex. Functions as scaffold that positions spliceosomal U2, U5 and U6 snRNAs at splice sites on pre-mRNA substrates, so that splicing can occur. Interacts with both the 5' and the 3' splice site (By similarity). {ECO:0000250}.

Subcellular Localization

Nucleus speckle {ECO:0000269PubMed:15169873}.

Disease Associations

Tissue Specificity

Strongly expressed in testis (preferentially in the outer cell layer), and moderately in ovary (preferentially in granulosa cells). {ECO:0000269PubMed:11275560}.
