Protein Structure
UniProt Annotation
Function Required to suppress inappropriate homologous recombination, thereby playing a central role DNA repair and in the maintenance of genomic stability. Antagonizes homologous recombination by interfering with the formation of the RAD51-DNA homologous recombination structure. Binds single-strand DNA and poly(A) homopolymers. Positively regulate the poly(ADP- ribosyl)ation activity of PARP1; however such function may be indirect. {ECO:0000269PubMed:20931645, ECO:0000269PubMed:22153967}.
Subcellular Localization Cytoplasm {ECO:0000250}. Nucleus {ECO:0000269PubMed:20931645, ECO:0000269PubMed:22153967}. Note=Localizes to chromatin in response to S phase arrest but not in mitosis. Targeted to chromatin via its interaction with PCNA.
Disease Associations
Tissue Specificity Restricted to testis. Overexpressed in multiple cancer cells. {ECO:0000269PubMed:20931645}.
