Is predicted to encode a protein with the following domains: Regulator of chromosome condensation, RCC1; Zinc finger, RING-type; Regulator of chromosome condensation (RCC1) repeat; Galactose-binding-like domain superfamily; Ring finger domain; Regulator of chromosome condensation 1/beta-lactamase-inhibitor protein II; PHR domain superfamily; PHR domain; PHR; APC10/DOC domain; and Zinc finger, RING/FYVE/PHD-type. Is an ortholog of C. elegans F07B7.12 and rpm-1. In C. elegans, rpm-1 is involved in several processes, including negative regulation of intracellular signal transduction; regulation of neuron projection development; and regulation of synapse assembly.
