Predicted to enable several functions, including catalytic activity, acting on a tRNA; flavin adenine dinucleotide binding activity; and ubiquitin-like modifier activating enzyme activity. Predicted to be involved in protein modification process and tRNA splicing, via endonucleolytic cleavage and ligation. Predicted to be part of transcription factor TFIID complex. Is an ortholog of C. elegans
uba-1. In C. elegans,
uba-1 is involved in several processes, including developmental process involved in reproduction; negative regulation of transcription by RNA polymerase II; and protein metabolic process.
