Uba1 - ubiquitin-like modifier activating enzyme 1

Predicted to enable ubiquitin activating enzyme activity. Predicted to be involved in cellular response to DNA damage stimulus; protein ubiquitination; and ubiquitin-dependent protein catabolic process. Predicted to be located in mitochondrion and nucleoplasm. Predicted to be active in cytoplasm and nucleus. Predicted to colocalize with bounding membrane of organelle; desmosome; and heterochromatin. Human ortholog(s) of this gene implicated in VEXAS syndrome and X-linked spinal muscular atrophy 2. Orthologous to human UBA1 (ubiquitin like modifier activating enzyme 1).
