The function of ENSG00000168005 (SPINDOC, spindlin interactor and repressor of chromatin binding) is as follows. Chromatin protein that stabilizes SPIN1 and enhances its association with histone H3 trimethylated at both 'Lys-4' and 'Lys-9' (H3K4me3K9me3) (PubMed:33574238). Positively regulates poly-ADP- ribosylation in response to DNA damage; acts by facilitating PARP1 ADP- ribosyltransferase activity (PubMed:34737271). .
