Positively stimulates PRMT1-induced protein arginine dimethylated arginine methylation (PubMed:28040436). Promotes colorectal cancer cell malignancy (PubMed:28040436). Homodimer (PubMed:28040436). Component of the tRNA-splicing ligase complex (PubMed:21311021, PubMed:24870230). Interacts with FAM98A (PubMed:28040436). Expressed strongly in colorectal cancer tissues compared to wild-type colon samples (at protein level) (PubMed:28040436). Expressed strongly in colorectal cancer tissues compared to wild-type colon samples (PubMed:28040436). Dubious isoform due to intron retention. Belongs to the FAM98 family.
