== Function ==
[https://www.uniprot.org/uniprot/SHPRH_HUMAN SHPRH_HUMAN] E3 ubiquitin-protein ligase involved in DNA repair. Upon genotoxic stress, accepts ubiquitin from the UBE2N-UBE2V2 E2 complex and transfers it to 'Lys-164' of PCNA which had been monoubiquitinated by UBE2A/B-RAD18, promoting the formation of non-canonical poly-ubiquitin chains linked through 'Lys-63'.<ref>PMID:17130289</ref> <ref>PMID:17108083</ref> <ref>PMID:18719106</ref>
