The PRP4K gene is the human homolog of Schizosaccharomyces pombe Prp4, which encodes a protein kinase that appears to be involved in pre-mRNA splicing (Gross et al., 1997). Based on kinase domain sequence, Prp4 belongs to the Clk (CDC-like kinase) family.
Using a PCR approach, Gross et al. (1997) identified human and mouse homologs of S. pombe Prp4. The human and mouse amino acid sequences are 98% identical, and the mammalian sequence shared 44% identity with that of the S. pombe protein. Gross et al. (1997) demonstrated that Prp4 and a recombinant fusion protein consisting of the yeast N terminus with the mouse kinase domain phosphorylated the human arginine/serine-rich splicing factor SFRS2 (600813) in vitro.
Stumpf (2024) mapped the PRP4K gene to chromosome 6p25.2 based on an alignment of the PRP4K sequence (GenBank AF283465) with the genomic sequence (GRCh38).
