Structural highlights
Disease
PARP9_HUMAN Overexpressed at significantly higher levels in fatal high-risk diffuse large B-cell lymphomas (DLB-CL) compared to cured low-risk tumors. Overexpression in B-cell lymphoma transfectants may promote malignant B-cell migration. May therefore be involved in promoting B-cell migration and dissemination of high-risk DLB-CL tumors.
Function
PARP9_HUMAN In concert with DTX3L plays a role in PARP1-dependent DNA damage repair. PARP1-dependent PARP9/BAL1-DTX3L-mediated ubiquitination promotes the rapid and specific recruitment of 53BP1/TP53BP1, UIMC1/RAP80, and BRCA1 to DNA damage sites. Involved in inducing the expression of IFN-gamma-responsive genes.[1] [2]
