Predicted to enable ubiquitin binding activity. Predicted to be involved in regulation of transcription, DNA-templated; rescue of stalled ribosome; and ribosome-associated ubiquitin-dependent protein catabolic process. Predicted to act upstream of or within DNA repair. Predicted to be located in nucleus. Predicted to be part of activating signal cointegrator 1 complex. Is expressed in several structures, including adrenal gland; alimentary system; aorta; brain; and genitourinary system. Orthologous to human ASCC2 (activating signal cointegrator 1 complex subunit 2). [provided by Alliance of Genome Resources, Apr 2022]
