Function

PRP19_HUMAN Plays a role in DNA double-strand break (DSB) repair. Binds double-stranded DNA in a sequence-nonspecific manner. Acts as a structural component of the nuclear framework. May also serve as a support for spliceosome binding and activity. Essential for spliceosome assembly in a oligomerization-dependent manner and might also be important for spliceosome stability. May have E3 ubiquitin ligase activity. The PSO4 complex is required in the DNA interstrand cross-links (ICLs) repair process. Component of the PRP19-CDC5L complex that forms an integral part of the spliceosome and is required for activating pre-mRNA splicing.^[1] ^[2] ^[3] ^[4] ^[5] ^[6]

Publication Abstract from PubMed

Human Pre-mRNA Processing factor 19 (hPRPF19) is an important component in human spliceosome machinery. hPRPF19 contains a WD40 repeats domain at its C-terminus, which is also conserved in yeast. Here we determined the crystal structure of the C-terminal WD40 repeat domain of hPRPF19 by X-ray crystallography. Our structural analysis revealed some significantly different structure features between the human and yeast Prp19 WD40 repeat domain. However, there are also conserved clusters of residues at the bottom surface of the fourth and the fifth WD40 repeats, which provides the important implication for the conserved Prp19 proteins in both human and yeast.
